Thinking about bricks and mortar: try to live a good life every day. Thinking about the trend: patiently wait for the trend to come.

People with brick-and-mortar thinking value tactical correctness far more than strategic correctness. They believe that things gradually accumulate from quantitative changes to qualitative changes. People who think from the outlet are just the opposite. They value strategic correctness far more than tactical correctness.

That is, engineers like to break down any complex things into simple modules that are easy to operate, and then solve them one by one.

There are no problems that cannot be solved, only costs that cannot be afforded

Although the rocket is extremely complex, it is nothing more than N parts built one by one. Just find the part you can get started with and get it done

Be as focused as a machine, not as scattered as a flashlight

The first stage is to set big goals and look at the overall situation

In the second stage, decomposition begins

The third stage is to determine what to do within a month.

The fourth stage, continue to break down to the to-do list

The fifth stage is to break it down into what to do in a day

The key to quantification is to know what to calculate, rather than obsessing over the results.

Test whether you can think about quantitative models of real life in an organized way

Write down, draw, and talk about the process of deduction, turn a variable into a scene or a story, and then follow the clues to find more variables

The first step is to find the variables that are easiest to think of

The second step is to find more variables through narrative and drawing methods.

The third step is to connect them through simple four arithmetic operations.

OKR: Objective and Key Results

An application management tool that organically combines engineering and quantitative thinking

Bacon once said: "Reading makes you enriched, talking makes you quick, and note-taking makes you accurate."

First, show priority

Second, make people focus

Third, it is conducive to deliberation

Fourth, save brain resources

Dynamic list - To do

Static List - Travel

In most cases, only two of the three points of good, fast, and cheap can be considered.
