I am the greatest.

Don't quit. Suffer now and live the rest of your life as a champion.

It's not bragging if you can back it up.

To be a great champion you must believe you are the best. If you're not, pretend you are.

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

You can't keep your mind on fighting when you're thinking about a woman. You can't keep your concentration. You feel like sleeping all the time.

Truly great people in history never wanted to be great for themselves. All they wanted was the chance to do good for others and be close to God.

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

Float like a butterfly, sting like a bee.

The greatest victory in life is to rise above the material things that we once valued most.
