Those with a high level of confidence may have as many or more weaknesses than those with low self-esteem. The difference is this; instead of dwelling on their handicaps, they compensate for them by dwelling on their strengths.
Let no one charge me with ever having abused or encouraged weakness or surrendered on matters of principle. But I have said, as I say again, that every trifle must not be dignified into a principle.
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 them 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 at best knows in the end the triumph of high achievement, and who at worst, if he fails, at least fails while daring greatly.
