If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, so thoughtful that it becomes a philosophy of life, — if, in short, I am an optimist, my testimony to the creed of optimism is worth hearing.
One can never consent to creep when one feels an impulse to soar.
Optimism is the faith that leads to achievement; nothing can be done without hope.
A happy life consists not in the absence, but in the mastery of hardships.
