promise yourself.

"Promise yourself: to be so strong that nothing can disturb your piece of mind; to make all your friends feel like there is something worthwhile in all of them; to think of only the best and to expect only the best; to forget the mistakes of the past and press on to the greater acheivements of the future; to give so much time to improving yourself that you have no time to criticise others; to be too large for worry, too noble for anger, too strong for fear, and too happy to permit the presence of trouble; to live in the faith that the whole world is on your side, so long as you are true to the best that is in you."
