does anyone know who came up with the adidas quote impossible is nothing?

Answer 1

Probably some marketing firm that Adidas paid big money for...however when I heard it...I thought it sounded like a quote from Gabriel Riqueti Mirabeau who said "Nothing is impossible to the man who will"

Answer 2

"Impossible is just a big word thrown around by small men who find it easier to live 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."
-Muhammed Ali
