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.
Personal courage is really a very subordinate virtue-a virtue, indeed, in which we are surpassed by the lower animals; or else you would not hear people say, as brave as a lion.
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.
If people bring so much courage to this world the world has to kill them to break them, so of course it kills them. The world breaks every one and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry.
