The reasonable man adapts himself to the world; the unreasonable one persists to adapt the world to himself. Therefore all progress depends on the unreasonable man.
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.
