Besides boxing, he was known for his quick wit, sharp tongue, and memorable quotes.
Here's one of my favorites.
“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. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
Here is a link to some great photos.
