10,000 hours (or thereabouts) of practice is one prerequisite. But you have to practice the right things. And for most people that means there needs to be some structure to their practice, some feedback from existing experts. Otherwise, how will you know what needs improvement or re-adjustment.

'There is no pleasure without pain.' Pleasure is progress, and pain the pain of effort. Study in the wrong way, however, and the result may be just pain with no pleasure at all. One must, without fail, learn the correct way to study."
