Perseverance is what will take you ever further, you will pass the levels, the levels much faster. The technical dimension will help you, but the mind is a much more important weapon. Let's take a simple example, modern tennis. For me, because I know it's debatable, they are two players of the same generation, one who inherited the talent (the closest in any case to Federer), and the other who is endowed with perseverance in incredible effort. The first did not win Grand Chelem, and the second won 17 titles in the Grand Chelem including 11 times Roland-Garros. One is Richard Gasquet, the other is Rafael Nadal.
