The athlete of today is not an athlete alone. He's the center of a team - doctors, scientists, coaches, agents and so on.
You can't climb up to the second floor without a ladder. When you set your aim too high and don't fulfill it, then your enthusiasm turns to bitterness. Try for a goal that's reasonable, and then gradually raise it.
An athlete cannot run with money in his pockets. He must run with hope in his heart and dreams in his head.
To boast of a performance which I cannot beat is merely stupid vanity. And if I can beat it that means there is nothing special about it. What has passed is already finished with. What I find more interesting is what is still to come.
