Happiness? That's nothing more than a good health and a poor memory.

Happiness? That's nothing more than health and a poor memory.

Happiness is nothing more than good health and a bad memory.

I don't know what your destiny will be, but one thing I know: the only ones among you who will be really happy are those who have sought and found how to serve.

Remembrance of things past is just for the rich. For the poor it only marks the faint traces on the path to death.

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
