Muhammad Ali

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

It's the repetition of affirmations that leads to belief. And once that belief becomes a deep conviction, things begin to happen.

If you even dream of beating me you'd better wake up and apologize.

It's hard to be humble, when you're as great as I am.

Age is whatever you think it is. You are as old as you think you are.

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

Service to others is the rent you pay for your room here on earth.

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

I believe in the religion of Islam. I believe in Allah and peace.

Allah's the Arabic term for God. Stand up for God, fight for God, work for God and do the right thing, and go the right way, things will end up in your corner.

If you lose a big fight, it will worry you all of your life. It will plague you — until you get your revenge.

The name Muhammad is the most common name in the world. In all the countries around the world — Pakistan, Saudi Arabia, Morocco, Turkey, Syria, Lebanon — there are more Muhammads than anything else. When I joined the Nation of Islam and became a Muslim, they gave me the most famous name because I was the champ.

There are more pleasant things to do than beat up people.

My toughest fight was with my first wife.

Silence is golden when you can't think of a good answer.

Float like a butterfly, sting like a bee.

Allah is the Greatest. I'm just the greatest boxer.
