One of the great lessons I've learned in athletics is that you've got to discipline your life. No matter how good you may be, you've got to be willing to cut out of your life those things that keep you from going to the top.
There are many people who could be Olympic champions. All-Americans who have never tried. I'd estimate more than 5 million people could have beaten me in the pole vault the years I won it... at least 5 million. Men that were stronger, bigger and faster than I was could have done it, but they never picked up a pole, never made the feeble effort to pick their legs off the ground trying to get over the bar.
It may sound strange, but many champions are made champions by setback. They are champions because they've been hurt. Their experience moved them, and they pulled out this fighting spirit, making them what they are. Sometimes in life, God gives us a difficulty in order to bring out the fighting spirit. Everything that happens to you can happen for good if you have this spirit. The essential thing in life is not in the conquering, but in the fight.
