The one who plants trees, knowing that he will never sit in their shade, has at least started to understand the meaning of life.

The great secret of true success, of true happiness, is this: the man or woman who asks for no return, the perfectly unselfish person, is the most successful.

If a man does not work at necessary and good things, then he will work at unnecessary and stupid things.

The sole meaning of life is to serve humanity.

If we have chosen the position in life in which we can most of all work for mankind, no burdens can bow us down, because they are sacrifices for the benefit of all; then we shall experience no petty, limited, selfish joy, but our happiness will belong to millions, our deeds will live on quietly but perpetually at work, and over our ashes will be shed the hot tears of noble people.

If you want love and abundance in your life, give it away.
