It is not the critic who counts, not 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 and and again and again, 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 knows at 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. Keep on fighting my friend, remember fainting but still fighting.
Words of Wisdom by Theodore Roosevelt.
