So I read the book he quoted - "Source of Power". And you know what? It has a tremendous overlap with Deliberate Practice.
The proponents of Deliberate Practice never claim to "just do it over and over" - you have to have background knowledge, a teacher/coach, etc... the tacit knowledge. Part of it is given to you and part of it is something that you're put into a position to experience for yourself.
It seems the "divide" is overstated.
