Muhammad Ali Impossible Quotations

Impossible is not a declaration. It's a dare.

I am the greatest. I said that even before I knew I was. Don't tell me I can't do something. Don't tell me it's impossible. Don't tell me I'm not the greatest. I'm the double greatest.

Impossible is nothing.

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

It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.
