It is not the critic who counts; not the man who points out how the strong man stumbles, 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, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the 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 cold and timid souls who know neither victory nor defeat.
— Teddy Roosevelt
Perseverance is a great element of success; if you only knock long enough and loud enough at the gate you are sure to wake up somebody.
— Henry Wadsworth Longfellow
There is great power in a resolution that has no reservations in it — a strong, persistent, tenacious purpose — which burns all bridges behind it and which clears all obstacles from its path and arrives at its goal, no matter how long it may take, no matter what the sacrifice or the cost.
— Orison Sweet Marden
Effort only fully releases its reward after a person refuses to quit.
