One of my favorite quotes from Theodore Roosevelt

“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 up short again and again. Because there is no effort without error and shortcomings, he who knows the great devotion, who spends himself in a worthy cause, who at the best knows in the end the high achievement of triumph and who at worst, if he fails while daring greatly, knows his place shall never be with those timid and cold souls who know neither victory nor defeat”.
