“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." ”

“Struggling and suffering are the essence of a life worth living. If you're not pushing yourself beyond the comfort zone, if you're not demanding more from yourself - expanding and learning as you go - you're choosing a numb existence. You're denying yourself an extraordinary trip.”

“Most people never get there. They're afraid or unwilling to demand enough of themselves and take the easy road, the path of least resistance. But struggling and suffering, as I now saw it, were the essence of a life worth living. If you're not pushing yourself beyond the comfort zone, if you're not constantly demanding more from yourself--expanding and learning as you go--your choosing a numb existence. Your denying yourself an extraordinary trip.”

“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.”

“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.”

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

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