Muhammad Ali

“Float like a butterfly, sting like a bee. His hands can't hit what his eyes can't see.”

“If my mind can conceive it, and my heart can believe it—then I can achieve it.”

“Don’t count the days; make the days count.”

“I am the greatest, I said that even before I knew I was.”

“A man who views the world the same at fifty as he did at twenty has wasted thirty years of his life.”

“He who is not courageous enough to take risks will accomplish nothing in life.”

“I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion.'”

“Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”

“Service to others is the rent you pay for your room here on Earth.”

“Friendship is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.”

“It isn't the mountains ahead to climb that wear you out; it's the pebble in your shoe.”
