This quotation has been attributed to Muhammad Ali but it may really be from an Adidas ad. I still like it:
“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.”
Ali was coming to the end of his career and a ferocious puncher like Shavers looked perfectly placed to take his title. Ali was badly hurt in the second but survived and his experience and sheer courage enabled him to regroup and fashion a points lead. By the end of the 14th Ali was exhausted – but from somewhere he summoned three more excellent minutes and even had Shavers shaking at the end.
