We make a living by what we get, we make a life by what we give.

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

Be such a man, and live such a life, that if every man were such as you, and every life a life like yours, this earth would be God's Paradise.

You get the best out of others when you get the best out of yourself.
