“If you can't run, then walk. And if you can't walk, then crawl. Do what you have to do. Just keep moving forward and never, ever give up.”

“Run when you can, walk if you have to, crawl if you must; just never give up.”

“The only one who can tell you "You can't" is you. And you don't have to listen.-Nike”

“If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward.”

“Never, however, do I take shortcuts. There is not path of least resistance in my training. What I do equates to hard manual labor, disciplined grunt work. Once you permit yourself to compromise, you fail yourself. You might be able to fool some people, but you can never fool yourself. Your toughest critic is the one you face every morning in the mirror.”

“Unless you're not pushing yourself, you're not living to the fullest. You can't be afraid to fail, but unless you fail, you haven't pushed hard enough." ”

“I wasn't born with any innate talent. I've never been naturally gifted at anything. I always had to work at it. The only way I knew how to succeed was to try harder than anyone else. Dogged persistence is what got me through life. But here was something I was half-decent at. Being able to run great distances was the one thing I could offer the world. Others might be faster, but I could go longer. My strongest quality is that I never give up.”
