Can you recommend any reading for that methodology ? Sounds intuitively correct, but would love to get more context

Don't have a book but here's some quick thoughts: 1. Biographies on, e.g., Chinese pianist Lang Lang. When he was ~9 he 'retired' (it's an extreme case but telling, can recommend). 2. If you want formal/mathematical/CS perspective, study Reinforcement Learning (e.g. Rick Sutton).
