I don't understand the general social disparagement of professional athletes. They have been through a filter the likes of which most of the rest of us have never experienced. Their skills and abilities are evaluated ruthlessly at every level -- if they come up short, they are out. The ones who make it are the best of the best at what they do. For each of them there are thousands of little league, high school and college athletes who did not. The people who make it through are the ones who are not only naturally gifted physically, but absolutely passionate about playing their sport. You have to be in order to put in the work needed to reach this elite level.

Mastering does not mean on elite level.

You can master something without taking it into extremes. It's more going through the ups and downs of learning and experiencing progress and lack thereof.
