Mr. president, I've been a citizen of the United States of America for thirty three years and was never invited to the White House. It sure gives me pleasure to be invited to the Black House.

Float like a butterfly, sting like a bee. The hands can't hit what the eyes can't see.

I am grateful for all my victories, but I am especially grateful for my losses, because they only made me work harder.

Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it.

I have the world heavyweight title not because it was 'given' to me, not because of my race or religion, but because I won it in the ring through my own boxing ability.

When I meet a new person, I don’t see race or religion. I look deeper. We must learn to satisfy our conflicts peacefully and to respect one another.

You got black people in an all-white country and they don't know nothing about themselves.
