"A man is great by deeds, not by birth."
"Vanity is my favourite sin."
"You have power over your mind - not outside events. Realize this, and you will find strength."
"You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand."
"Big results require big ambitions."
