Theodore Roosevelt
It is not the critic who counts, nor the man who points out how the strong man stumbled, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes short again and again, who knows great enthusiasms, great devotions, who spends himself in a worthy cause, who, at the best, knows in the end the triumph of high achievement, and who, at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those timid souls who know neither victory nor defeat.
Far and away the best prize that life has to offer is the chance to work hard at work worth doing.
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 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.
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.
Whenever you are asked if you can do a job, tell'em, Certainly I can ! - and get busy and find out how to do it
Far better is it to dare mighty things, to win glorious triumphs, even though chequered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the grey twilight that knows not victory or defeat.
Do what you can, with what you have, where you are !
