It is not the critic who counts, nor the man who points out how the strong man stumbles or when the doer of deeds could have done 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, and who, at the worst, if he fails, at least he fails whilst daring greatly – so that his place shall never be with those cold and timid souls who know neither victory nor defeat…for those who have had to fight for it, life has truly a flavour the protected shall never know.
