You're so right with the analogy to physical training. Practice makes perfect. Also, I don't think its any coincidence that trainers of professional athletes often vary up their regimens with mental exercises. I think both types of people should diversify their training.

Could you expand on what you mean by "make sure you... don't learn the wrong way"? If you'd rather email me, I'm at levi -at- coderscoloringbook.com.
