The best executive is the one who has sense enough to pick good men to do what he wants done, and self-restraint to keep from meddling with them while they do it.
Speak softly and carry a big stick; you will go far.
In any situation, the best thing you can do is the right thing; the next best thing you can do is the wrong thing; the worst thing you can do is nothing.
In any moment of decision, the best thing you can do is the right thing. The worst thing you can do is nothing.
Far better is it to dare mighty things, to win glorious triumphs - even though checkered by failure - than to rank with those poor spirits who neither enjoy much nor suffer much, because they live in a gray twilight that knows not victory nor defeat.
Each time we face our fear, we gain strength, courage and confidence in the doing.
Do what you can, with what you have, where you are.
