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 will 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 know, a thousand times no, until all the nos become meaningless. All your life they will tell you no, quite firmly and very quickly. And you will tell them yes. — Nike ad
