I love this quote from Nadal, a lot of hobbyists as well as pros could learn from it:
I don’t understand going on court just to practise,” he says. “I go on court to improve something. That’s the way that I understand my career, the way that I understand sport. I really don’t find the motivation to go on court if I don’t have the goal of trying to do something better. And when the day arrives when that is not the case, that’s going to be the day that I’ll take a boat out and go fishing.
Nadal believes the desire to improve is the very essence of sport. “If you don’t have the will to improve, you don’t understand sport, because sport is always about improving,” he says. “That’s the meaning of sport. It’s playing with the dream of doing something better than what you were doing before. When you’re not working with the passion to do something better, I think that sport loses its sense.
