'I can't' are two words that have never been in my vocabulary. I believe in me more than anything in this world.
Winning is great, sure, but if you are really going to do something in life, the secret is learning how to lose. Nobody goes undefeated all the time. If you can pick up after a crushing defeat, and go on to win again, you are going to be a champion someday.
The triumph can't be had without the struggle.
