The only man who makes no mistakes is the man who never does anything.

When you are asked if you can do a job, tell 'em, 'Certainly I can!' Then get busy and find out how to do it.

Let us rather run the risk of wearing out than rusting out.

The credit belongs to the man who is actually in the arena; whose face is marred by sweat and blood; who strives valiantly; who errs and comes short again and again because there is no effort without error and shortcoming; who knows the great enthusiasms, the great devotion, spends himself in a worthy cause; who at best knows in the end the triumph of high achievement; and who at worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who have never tasted victory or defeat.

In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing

Far better is it to dare mighty things, to win glorious triumphs, even though checked 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.
