"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 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 or shortcoming, but who knows the great enthusiasms, the great  devotions, who spends himself for 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 he fails while daring greatly, so that his  place shall never be with those cold and timid souls who knew neither  victory nor defeat."  Theodore Roosevelt   "Citizenship in a Republic,"  Speech at the Sorbonne, Paris, April 23, 1910
