Courage is not having the strength to go on, it is going on when you don't have the strength. Industry and determination can do anything that genius and advantage can do and many things that they cannot.
The credit belongs to those who are actually in the arena, who strive valiantly; who know the great enthusiasums, the great devotions, and spend themselves in a worthy cause; who at best know the triumph of high achievement; and who, at worst, if they fail, fail while daring greatly, so that their place shall never be with those cold and timid souls who know neither victory nor defeat.
