How to be an expert.... apparently the answer is to practice. Not just repeating but how you practice. Here is a quote:

"For the superior performer the goal isn't just repeating the same thing again and again but achieving higher levels of control over every aspect of their performance. That's why they don't find practice boring. Each practice session they are working on doing something better than they did the last time."
