Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.
"You may believe that you are responsible for what you do, but not for what you think. The truth is that you are responsible for what you think, because it is only at this level that you can exercise choice. What you do comes from what you think."
Respect the past in the full measure of its desserts, but do not make the mistake of confusing it with the present nor seek in it the ideals of the future.
