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

Impossible is not a declaration. It is a dare.

Impossible is potential.

Impossible is temporary.

Impossible is nothing!

Fifteen referees. I want fifteen referees to be at this fight because there ain't no one man who can keep up with the pace I'm gonna set except me. There's not a man alive who can whup me.

The fight is won or lost far away from witnesses - behind the lines, in the gym and out there on the road, long before I dance under those lights.

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