Herschel Walker: My sister, she is a little bit over a year older. She was fast, and I was that chubby kid. And she was always beating me; she always beat me. I just felt that I couldn’t see a girl beating me all the time.  And I said, “I’ve got to beat her. I’ve got to beat her.” And I just trained and trained, and every time I went up to race her, she beat me. Every time I went up, she beat me. And after you’ve been beat over ten times, sometimes people got a tendency of quitting. And I said, “No, I’m not going to quit. I’m not going to quit.” And I kept doing it until I got where I could beat her. And what was so strange about it is the first race that I ever beat her, I barely beat her. But I think that was the springboard.  Once I saw I can do it, I said, “Uh-oh, now it’s a little different. Now I’m ready.” And I think that’s the way the mind works. Sometimes you may not think you can do it. You may not think you can do it, but as long as you’ve got that doubt, you’re never going to do it. I think that’s what happened. By me continuing to want to race — and continuing to want to race her — sometime you’ve got to win.
