La qualité de tes résultats est proportionnelle à la qualité de ton entraînement.
I know, from long experience, that if you make an effort in training when you don’t especially feel like making it, the payoff is that you will win games when you are not feeling your best. That is how you win championships, that is what separates the great player from the merely good player. The difference lies in how well you’ve prepared.” — Rafael Nadal
