"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... 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 he fails while daring greatly."

Theodore Roosevelt - April 23rd, 1910
