“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, who 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 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 neither know victory nor defeat.”
― Theodore Roosevelt

“You cannot let a fear of failure, or a fear of comparison, or a fear of judgement stop you from doing what's going to make you great. You cannot succeed without this risk of failure, you cannot have a voice without the risk of criticism and you cannot love without the risk of loss. You must go out and take these risk. … Do what’s uncomfortable, and scary, and hard, but pays off in the long run. Be willing to fail. Let yourself fail. Fail in the way and the place where you would want to fail. Fail, pick yourself up and fail again. Because without this struggle, what is your success anyway?”
― Charlie Day
