"The one who knows that he doesn't know anything, knows more than the one who doesn't know that he doesn't know anything."
"If we don't have the key, we can't open whatever it is we don't have that it unlocks. So what purpose would be served in finding whatever need be unlocked, which we don't have, without first having found the key what unlocks it?"
Always dream and shoot higher than you know you can do. Don't bother just to be better than your contemporaries or predecessors. Try to be better than yourself.
-- William Faulkner
