minimalist learning method
Preface
The original intention of writing this book
Part One: The concept and three major advantages of minimalist learning method
Section 1 Minimalist closed loop: input digestion output, learn everything in three steps
Input: Enter the knowledge you want to learn
Digestion: Understanding and understanding what you want to learn
Output: Put the learned knowledge and skills to use
Section 2: Pursuit of accuracy: backward thinking, what to use to learn and what not to do useless work
The second biggest advantage of the minimalist learning method is: "Pursue accuracy, don't do it without learning."
The goal should be clear enough and specific enough.
Section 3: Go straight to the essence: learn from the roots, and know everything
Input from the essence: In the input process, the minimalist learning method advocates choosing the most essential things to learn.
Digest from the root: In the digestion process, it is also emphasized that in the process of understanding, we must explore the essence and not just understand the surface; only by understanding from the root can we truly understand.
McKinsey’s “MECE” principles:
The full English name is Mutually Exclusive Collectively Exhaustive. Chinese means "mutually independent, completely exhaustive"
For a major topic, it is necessary to classify it without overlap or omission.
Part 2: Accurate input: Use the right posture to learn accurately
Section 1: Learning Accurately: Thinking Backwards and Learning Knowledge That Directly Determines Results
Push forward from the results to discover the crux of the problem, and then conduct special study on this part of the problem. Study wherever you can improve your scores.
Only learn the part of knowledge that can directly affect the final result, start with the end in mind, and go straight to the result. This is the underlying guarantee for efficient learning.
Three steps to learn accurately:
1. Changing Consciousness: You must study with a truly effective purpose
2. Set goals: deduce the implementation process and formulate achievable goals
S: Specific
The first principle of setting goals means that the goals should be clear and specific, rather than vague and general.
M: Measurable
Refers to a clear set of data that can be used as a basis for measuring whether the goal has been achieved.
A: Attainable
It means that the goal is not too lofty, but can be achieved in reality.
R: Relevant
This means that your goals should be related to your other goals, or to the overall goals of the organization.
T: Time-bound
It means that the goal should be completed within a certain period of time, not in the distant future.
SMART rules
3. Scientific execution: keep a close eye on goals and reject excuses
Backward thinking is goal-oriented thinking.
Only by keeping an eye on your goals at all times can you truly ensure the achievement of your goals.
In the learning process, there are too many factors that interfere with achieving your goals.
First, imagine the end result. Second, work backwards from the results to the implementation process. Third, break it down into achievable tasks. Fourth, keep an eye on the goals and implement them scientifically.
Section 2: Choose the right one: The best learning materials are those that suit you
1. Exam-based learning: Textbooks and syllabus are the best learning materials
1. The syllabus is the criterion for everything
Exam-based learning means that the ultimate goal of our learning is to pass the exam
2. Textbooks are the best learning materials
The exam you take has official textbooks, which are the best study materials.
If the test score is less than 80% of the total score, it must be because you did not get the scores for all the basic questions. Return to the textbooks and understand the textbooks thoroughly.
Transparent: understand clearly and know why.
Complete: Leave no doubt, the particles will be returned to the warehouse.
String: form a system and string together knowledge.
The easiest way: read the directory
A more advanced approach is: close the book, take out a piece of paper, and draw the knowledge structure diagram of the book on the paper. While drawing, think about the specific knowledge in each part, so that you can really understand this textbook. I have thoroughly understood the knowledge points and formed my own system.
More: Repeatedly, again and again.
2. Continuous learning: sticking to the end is more important than choosing anything
1. Studying materials is not the first priority, learning to the end is the first priority
2. If you still have to choose, how should you choose?
First, look at the brand.
old brand
famous brand
Emerging brands
Second, look at word of mouth.
Ask people in the circle
Read word-of-mouth posts
Third, try it yourself
3. Pursuing the essence: learning from the root, metacognition points directly to the cornerstone
The minimalist learning method has a core principle, which is "essential thinking".
1. Look at the cornerstone works to help you quickly grasp the essence.
First, most of these cornerstone works are books.
Second, there are some cornerstone works, which are certain papers that pioneered this field.
Third, there are some cornerstone works that are simpler, just one or two concepts about the essence of this field.
2. To learn key methodologies, “5 hours of theory” is more important than “10,000 hours of theory”
Become a master in your field by learning rather than mastering it
3. Understand 100 keywords: McKinsey consultants quickly master an industry
First, know 100 keywords first.
For example, if you want to understand the advertising industry, then you first understand the keywords such as "CPM, CPS, CPC, conversion rate" and so on. Then you will understand most of this industry.
For another example, in the e-commerce industry, if you understand the formula "sales = traffic × conversion rate × customer unit price", you will master the basic logic of this industry, because the field of e-commerce is all working around this formula. .
Second, find 3 to 5 experts and sit down and talk with them for half a day to a whole day.
Third, find 3 to 5 monographs and read them carefully.
Section 3: Learn well: input new knowledge and make "sandwich cake"
1. Preview before learning: the key is to grasp the degree
Step 1: Before learning, preview to reduce the difficulty of formal learning. During the preview process, mark the doubt points so that you can focus on them during formal learning.
Point 1: The knowledge is interrelated, and the preview effect will be better after review.
Point 2: Don’t become “advanced learning”, just mark the difficult points.
Point 3: Overall preview during the winter and summer vacations, the key way to surpass your academic masters.
2. Study with purpose: Grasp the purpose and pay attention to doubt points
Step 2: When studying formally, regardless of whether you are following others in class or studying on your own, this step is to have a clear purpose and understand everything you don't understand. This is the key to everything.
Method 1: Focus on what you didn’t understand during the preview.
Method 2: Pay attention to the beginning and the end, and follow the teacher through the knowledge chain again.
Method 3: If you don’t understand anything in class, ask immediately.
3. Reviewing after studying is the most easily forgotten step.
Step 3: After you finish studying, remember to review in time, so that the effect will be better. On the one hand, it will eliminate "false understanding", on the other hand, it will prevent forgetting and deepen understanding.
Before doing your homework, you should review what you learned that day.
"Sandwich Cake Learning Method": Preview before learning, then study formally, and finally review
Part Three: Deep Digestion: How to Thoroughly Understand Knowledge
Section 1: Mental preparation: either have a blunt sense, or have unconditional self-confidence
1. With the power of insensitivity, you will complete deep digestion without realizing it.
In the process of deep digestion, we might as well be a "big-hearted person" and have a more indifferent attitude. If you don’t understand it, you just don’t understand it. It doesn’t matter. I will just continue to learn.
"Others do the same thing":
When you are dissatisfied with your performance and feel frustrated, you tell yourself "I am not a god, others are the same". In this way, your mentality will instantly improve, let yourself go, and forgive yourself.
2. Unconditional self-confidence: Get rid of "fear of difficulties" and you can learn everything
The attitude of top academics in studying weak subjects is: face the difficulties and attack the subjects that are not working well.
Start by believing, forget about the difficulties in front of you, and throw away your fear of difficulties.
Please believe in yourself unconditionally: you can learn everything! Start by being brave, keep at it, and you can do it!
Section 2: Accurate self-examination: Please be extremely honest and find loopholes in three ways
How do we find out the parts we don't understand?
The first aspect is that you must have the right mentality
The second aspect is that you have to have the right method
1. Self-examination is anti-human. You must be extremely honest.
Two or three methods of accurate self-examination, there is no way to escape the loopholes
1. Source self-examination: self-test with checklist
Source self-examination is to conduct self-examination based on the source of "what to learn".
To put it simply, have you learned everything you need to learn?
Textbook study: Check against the table of contents
Study for exams: Check against the syllabus
2. Result self-check: self-check according to the output
(1)Analyze examination papers
The greatest value of the test paper is that it allows you to find your own problems and fill in the gaps.
effect:
First, identify the weak sections.
Second, identify weak details.
Third, find out the reasons for losing points.
Use three questions to check yourself
The first question: Have I really understood all the knowledge points?
Second question: Can I use this knowledge point to solve problems?
Question 3: What went wrong during my exam?
careless exam
Exam mentality
a matter of time
(2)Analyze works
In order to acquire a certain skill through learning, it is more suitable to use the method of "analyzing works" to conduct self-assessment.
3. Others help test: Find these two kinds of people
(1) Find an expert to help you solve your doubts
(2) Find students and verify teaching
First, you feel that you cannot explain clearly or clearly.
There is no doubt that if you cannot explain something clearly, it is most likely because you have not learned it thoroughly.
Second, what the other party doesn’t understand.
What the other party doesn’t understand is most likely something you haven’t learned clearly.
Third, if you don’t understand something, the other party can’t understand it either.
Section 3: Really Win: Do these three points and you will be able to thoroughly understand everything
When we already know what we have not learned clearly and thoroughly, the next thing we have to do is to thoroughly understand what we do not understand.
1. Critical start: within 72 hours, start from where you can start
There are only so many types of subjective questions in Chinese language, and they all have fixed ideas for answering questions.
1. It doesn’t matter where you start, the beginning itself is important.
2. You must act within 72 hours, otherwise it may never start.
3. It’s easiest to start by applying the known to the unknown.
2. Overcoming Difficulties: Deep Focus, Attack One at a Time
Change "passive learning" to "active learning"
1. Be proactive in exploring rather than passively accepting.
Deeply focused learning requires you to be very clear about the purpose of learning.
2. Calm down and eliminate all distractions
Physical isolation: being separated from the source of interference in time and space.
Isolation of trivial matters: When you want to focus deeply on your studies, you must either ask others to do the trivial things that affect your energy but must be done, or you can simply ignore them. For example, if you are worried that your mobile phone will interfere with you, you can simply put your mobile phone away. You are far away.
3. Concentrate your efforts and solve one problem at a time
3. Using external forces: Let foreign aid play a real role
1. When do you need to rely on external help?
In the first case, the learning effect is relatively poor and cannot keep up with the pace of learning.
Seek help from appropriate foreign aid, find external forces that are useful to you, and study in a targeted manner under the guidance and influence of external forces, so that you will improve faster.
In the second case, you study hard but never make a breakthrough.
One possibility is that your current learning method is no longer suitable for what you are learning.
Another possibility is that your learning ability and cognitive ability have reached the limit, and the new knowledge has exceeded your ability and cognitive scope.
Need help from outside - experts or teachers
The third situation is to suddenly improve scores before the exam and scientifically achieve "cramming".
In the fourth case, if you want the learning effect to be better than that of ordinary people, you need to increase the intensity.
Specifically, in the process of learning, the difficulty is artificially increased and the standards are required to be higher than the requirements of the learning itself.
"Raising the dimension and then reducing it"
2. Two steps for selecting foreign aid
First, clarify the purpose of borrowing external forces.
No matter what you do, the clearer your purpose, the more precise your execution will be.
Several purposes at the same time, sort them
Second, choose the “right external force” scientifically.
Primary school teachers understand students’ way of thinking better and have the advantage of “understanding teaching”
The core advantage of an excellent middle school and high school teacher is “knowledge”
The best teachers and foreign aid must both "understand teaching" and "understand knowledge"
3. The biggest role of making good use of external forces may not be to teach you lessons.
In addition to teaching you knowledge and allowing you to understand it, external forces also have another very important responsibility, which is to answer questions for you and provide feedback on your learning during your learning process, so that the comprehensive effect will be better .
Part 4: Multiple output: four layers of output to truly use knowledge
The first section is expressive output, that is, speaking out the knowledge learned and telling it to others.
The first level of output is expression, speaking out the learned knowledge.
1. Tell others
First, the person you are explaining to does not understand the knowledge, or does not understand it thoroughly.
Second, the person you are explaining to should give you feedback so that you can accurately judge yourself through its feedback.
Third, learn again based on feedback and simplify your expression.
Precautions
2. Tell it to yourself
First, talk to yourself, ask and answer questions to yourself.
Close the study book and speak it yourself.
Second, speak to yourself first, and then listen to yourself.
You can use your mobile phone or other recording device to record what you are saying while speaking.
For better results, you can listen to the recording the day after or a few days later.
3. Write to yourself
Write down what you have learned. If you can write it down easily, you have learned it clearly.
For example, when you read a book, you can write your thoughts after reading it and make a mind map of the book. These are very good application methods.
practice
The second section is problem-solving output, that is, using the learned knowledge to solve the problem.
1. Effectively answering questions is a process of constantly breaking through the comfort zone
Breaking out of your comfort zone is a great way to grow as a person quickly.
Two very bad but very common habits of writing questions
The first habit is to only answer the questions you know.
The second habit is to grind hard problems.
The process of answering questions is actually the process of constantly breaking through your comfort zone. The questions you want to answer must be questions that are beyond your comfort zone, but you cannot go beyond your comfort zone too much. If you go beyond it, it will be too difficult. You can do it completely. There is no point in not coming out.
2. Special topic brushing, a once and for all method of brushing up questions
1. Why do we need special topics? Why can it be done once and for all?
The core method of topic brushing is to focus on a certain type of questions or a certain type of knowledge section for a period of time.
In the process of answering questions, you need to summarize and study this kind of questions in depth, which is equivalent to thinking about this thing in your head for a period of time. The effect of answering questions will definitely be better.
Especially suitable for you to use to conquer your weak areas.
You need to use your most efficient time period to do this, so that the effect is more guaranteed.
2. Solve special topics and master the golden four steps
The first step is to review knowledge.
Understand the knowledge first before starting to answer special questions, rather than starting when you have only half-understanding.
The second step is to review the questions for the first time.
The core purpose is to solve problems directly based on known knowledge.
The first is that you can solve the problem based on the knowledge you already know. You may not be very proficient, but you can still solve it.
The second is that although you understand the knowledge, but because you have not applied it too much, or you are not very proficient in mastering the knowledge, you cannot solve some questions, or you can only solve part of them.
Re-consolidate your knowledge based on the topics you don't know.
The third step is to summarize the rules.
An important purpose of conducting special topic brushing is to find common problem-solving methods and problem-solving ideas in this type of questions.
The fourth step is to review the questions for the second time.
By brushing up on the questions, we can become more familiar with these methods and rules, and become familiar with them, ensuring that we can solve them quickly when we encounter such questions again.
How to get the best results in brushing questions
Section 3, exam output, how to scientifically score points
1. An interesting triangle relationship in the exam
To get high scores you need to do two things:
First, have the thinking of the question maker.
Second, he has strong scoring skills.
2. Possessing the thinking of the question maker is the prerequisite for getting high scores in the exam.
1. What is the question maker’s thinking?
The questions that come out must be "based on the teaching materials and examination syllabus."
Sometimes the college entrance examination questions will stipulate that there can be a certain proportion of over-the-top questions.
In essence, it is "putting yourself in someone else's shoes", imagining yourself as the person who asked the question, and imagining what the person who asked the question was thinking when they asked the question, and what they really want to test.
2. How to train the question maker’s thinking
Developing the "question maker's thinking" is a shortcut to get high scores in science, and it is also the only way to get high scores.
(1) Study real questions: Find patterns from real questions
(2) Develop a habit: Ask yourself more about what knowledge points you want to test in this question
3. Reference answer learning method: the guarantee of getting high scores in the exam
1. Why reference answers are so important
If you want to score high on the exam, you need to practice so that your answers come closest to the standard answers.
First, the standard answers to previous real questions.
Second, high-quality tutoring materials and reference answers to simulation questions.
2. Learn the three keys and four steps of reference answers
three keys
Answer structure: It is the skeleton of the answer, the structure that connects the entire answer. This is the first thing to learn.
Scoring points: The exam is basically based on scoring points, and the points correspond to "scoring keywords" and key steps.
Subject terminology: appearing professional
four steps
answer
Write the answer yourself first.
look
Compare the difference with the standard answer.
build
Modify your answer based on the standard answer.
After you find out your own problem, you can then carefully revise the standard answers one by one until they are consistent.
answer
Then answer your own questions until they are consistent with the standard answers.
Do this step after an interval of one or two days
3. Summarize the answer template and secure high scores.
The larger the exam, the more standardized the rules are, and the easier it is for you to follow the answer template.
As long as you summarize the question type, you will find that the answer is certain and not that broad.
Section 4: Use knowledge to do things, that is, use the knowledge you have learned to solve problems in the real world and truly use the knowledge. This is the ultimate goal of our learning.
Practical application, grasp the "33 principles"
1. After learning the knowledge, use it at least 3 times
If you want to really use it, you need to apply it immediately after learning the knowledge, and you must use it "at least 3 times." The more times you use it, the better the effect will naturally be.
2. Grasp the essence and draw inferences from one instance to another
How to do it: Four words: capture the essence!
"Ability to Analogy" Required
For example, in the field of financial management, don’t put your eggs in one basket.
An analogy in life and work is that we must have a plan B at any time
An analogy when farmers are farming is to not just plant one type of crop a year.
Section 5 Practice makes perfect, how to do it with deliberate practice
Deliberate practice is a common learning method and is the only way to become a master.
First determine the goals you want to achieve through practice, continue to break through the boundaries of your abilities during practice, and have a mentor or coach give feedback on your performance, improve step by step, and finally achieve your goals.
Three key takeaways:
1. Targeted practice
Exercise goals are used to determine whether the exercise is effective
Will think about which links have problems and conduct targeted exercises and improvements
2. Breaking through the boundaries of capabilities bit by bit
Any practice and growth is gradual.
Set a goal slightly higher than your current ability, and then raise the goal after reaching it
3. Feedback should be given during practice
Suggestions from experts in related fields are the best way to give feedback
Feedback from others during practice
Father, like son.
I am also a good feedback giver myself.
Part 5: Best state, three good helpers for minimalist learning
Section 1: Three steps to fall in love with learning and gain endless motivation
The first step: push back the dream and awaken the desire in your heart.
Work backwards from your dreams to build a roadmap for realizing them
Step 2: Visualize your dreams to make your motivation more reliable.
After experiencing the feeling of having something, you will be afraid of losing it and will be more eager to get it.
Step 3: Reward yourself. The more you learn, the more motivated you will be.
Reward yourself based on improved performance to keep yourself motivated.
If you want to achieve good learning results, you must make yourself fall in love with learning itself and connect learning with your dreams.
Section 2: Don’t be obsessed with self-discipline, habits are actually more important
1. The “limited nature” of self-discipline determines its unreliability
The essence of self-discipline is actually self-control.
Human self-control is limited.
2. Habit is a more reliable choice
How can a person stick to something?
Just meet one requirement: getting more than you give. That is: get-pay>0.
Improve "get"
Apply the knowledge we learn to different fields by drawing inferences from one example
Doing something you love will definitely make you satisfied and happy, and it will also improve your "getting".
Reduce effort
Reduce study time
Improve the efficiency of individual matters
Reduce the self-control consumed in the learning process
The best way is to "make it a habit"
Developing good habits will reduce the consumption of self-control.
Fixed study time:
Try to fix your study time as much as possible, start studying at this time, and make it a part of your life.
Fixed learning method:
Fixed study place:
Section 3: Get rid of procrastination, it only takes three seconds
1. Accept that “everyone procrastinates”
Accept procrastination and don't waste your energy due to the irritability, uneasiness, and inner struggles caused by procrastination.
2. Let’s start: a small ritual of three seconds
Say 1, 2, and 3 silently to yourself, or you can say it out loud.
After that, you start your study immediately and do what you should do.
3. Keep doing it: just do it for two minutes first
Two minutes is an imaginary finger, it could be three minutes, or five minutes. This time is the time you can allow yourself to persist in doing one thing.
4. Do the hard things first: higher ranks eliminate procrastination
The rationale: Based on a seven-hour work day, one hour of pain plus six hours of happiness is obviously more cost-effective than one hour of happiness plus six hours of pain.
