The secret of happiness is renunciation.

Whatever I engage in, I must push inordinately.

Wealth is not to feed our egos but to feed the hungry and to help people help themselves.

The sound rule in busi­ness is that you may give money freely when you have a sur­plus, but your name never-nei­ther as en­dorser nor as mem­ber of a cor­po­ra­tion with in­di­vid­ual li­a­bil­ity

Concentrate your energies, your thoughts and your capital. The wise man puts all his eggs in one basket and watches the basket.

A sunny disposition is worth more than fortune.

As I grow older, I pay less attention to what men say. I just watch what they do.
