the book titled How to Be Like Mike, there was an advert that is perhaps the elder to the adidas, Impossible Is Nothing,...the Nike "YES":
All your life you are told the things you cannot do.
All your life they will say you're not good enough
or strong enough or talented enough,
they'll say you're the wrong height or
the wrong weight or the wrong type to play this
or be this or achieve this.
They will tell you No,
a thousand times no
until all the nos become meaningless.
All your life they will tell you no,
quite firmly and very quickly.
They will tell you no.
And you will tell them Yes.
Tell them YES...gently, quietly, silently. But tell them YES.
