You don’t think. It’s all instinct. If you stop to think, you’re gone.

Sugar Ray Robinson

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

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

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, three-time World Heavyweight Champion, who is widely considered to be one of the best heavyweight boxing champions ever.

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

Floyd Mayweather Jr.

I’m not in this sport to see how hard I can get hit or to see how many big punches I can take. I am in this game to fight as long as I can. I am trying to dish a lot of punishment.

Floyd Mayweather Jr.

Champions aren’t made in gyms, champions are made from something they have deep inside them – a desire, a dream, a vision. They have to have last-minute stamina, they have to be a little faster, they have to have the skill and the will. But the will must be stronger than the skill.
