You ever heard of the 10,000 rule? It states that for you to be exceptional at something, you have to train at it for ten thousand hours. It may sound like a far-fetched rule, but it works. The basis of it in this context is if you want to become a successful footballer, you need to train, train, and train some more. There's never enough knowledge to know or skills to have when it comes to football. You always need to learn more in order to stay at the top of the pack. You should, however, learn how to balance learning and training. You can take the time to learn a new skill, then spend some more time trying to execute the move.
