The theory of deliberate practice is that you must practice in the learning zone. You can do it with a little challenge, don't practice in the panic zone. Don't practice within your comfort zone either, because comfort zones tend to become automatic. With automation, there is no room for growth.

Accept the pain and stay focused. Practicing in the learning area is a little more painful. We call this pain "growing pains" Pain means you are growing. Without pain, there is no growth. Jack Ma once said, "Pain is a man's nourishment." So if you stay in pain, you will be nourished.
