Happiness is nothing more than good health and a bad memory. — Albert Schweitzer. German polymath (1875–1965) Happiness, Health
I don't know what your destiny will be, but one thing I do know: the only ones among you who will be really happy are those who have sought and found how to serve.
You must give some time to your fellow men. Even if it's a little thing, do something for others - something for which you get no pay but the privilege of doing it.
Until he extends his circle of compassion to include all living things, man will not himself find peace.
