It isn't the mountains ahead to climb that wear you out; it's the pebble in your shoe.
He who is not courageous enough to take risks will accomplish nothing in life.
I done wrestled with an alligator, I done tussled with a whale; handcuffed lightning, thrown thunder in jail; only last week, I murdered a rock, injured a stone, hospitalised a brick; I'm so mean I make medicine sick.

I know where I'm going and I know the truth, and I don't have to be what you want me to be. I'm free to be what I want.
If you even dream of beating me you'd better wake up and apologize.
It's just a job. Grass grows, birds fly, waves pound the sand. I beat people up.
There are no pleasures in a fight but some of my fights have been a pleasure to win.
Life is a gamble. You can get hurt, but people die in plane crashes, lose their arms and legs in car accidents; people die every day. Same with fighters: some die, some get hurt, some go on. You just don't let yourself believe it will happen to you.
Only a man who knows what it is like to be defeated can reach down to the bottom of his soul and come up with the extra ounce of power it takes to win when the match is even.
The man who has no imagination has no wings.

Wars of nations are fought to change maps. But wars of poverty are fought to map change.
Hating people because of their color is wrong. And it doesn't matter which color does the hating. It's just plain wrong.
My only fault is that I don't realize how great I really am.
What keeps me going is goals.
The word 'Islam' means 'peace.' The word 'Muslim' means 'one who surrenders to God.' But the press makes us seem like haters.
Ali's got a left, Ali's got a right - when he knocks you down, you'll sleep for the night; and when you lie on the floor and the ref counts to ten, hope and pray that you never meet me again.

I've seen George Foreman shadow boxing, and the shadow won.

My principles are more important than the money or my title.
No one knows what to say in the loser's locker room.

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.

The fact is, I was never too bright in school. I ain't ashamed of it, though. I mean, how much do school principals make a month?

The Nation of Islam's main focus was teaching black pride and self-awareness. Why should we keep trying to force ourselves into white restaurants and schools when white people didn't want us? Why not clean up our own neighborhoods and schools instead of trying to move out of them and into white people's neighborhoods?
Terrorists are not following Islam. Killing people and blowing up people and dropping bombs in places and all this is not the way to spread the word of Islam. So people realize now that all Muslims are not terrorists.

Some of the titles were, 'The Intoxication of Life,' 'The Purpose of Life,' 'The Real Cause of Man's Distress,' 'The Journey to the Goal in Life,' and, one of my favorites, 'The Heart of Man.' They contained important insights that spoke to something deep inside me.
