When I was a young fellow I was knocked down plenty. I wanted to stay down, but I couldn’t. I had to collect the two dollars for winning or go hungry. I had to get up. I was one of those hungry fighters. You could have hit me on the chin with a sledgehammer for five dollars. When you haven’t eaten for two days you’ll understand.

Jack Dempsey

Don’t count the days, make the days count.

Muhammad Ali

To be a champ you have to believe in yourself when no one else will.

Sugar Ray Robinson

Getting hit motivates me. It makes me punish the guy more. A fighter takes a punch, hits back with three punches.

Roberto Durán

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

Muhammad Ali

I’ve never shown my weakness. I will never show my weakness.
