Deliberate Practice Turns Into Mental Representation

As you develop a skill through deliberate practice, you repeat the component parts of the skill enough times through repetition so that the brain chunks together all of the parts in the sequence. It eventually turns into a mental representation.

At that point, the brain can reproduce all parts sequentially without thought in a consistent manner. The brain then looks at all the parts coming together as one thing.

The brain then passes off the skill to your long-term memory. With repetition, it becomes easier for you to fire this skill circuit at higher levels with less visual data input. And no thought.
