Happiness lies in being privileged to work hard for long hours in doing whatever you think is worth doing. One man may find happiness in supporting a wife and children. Another may find it in robbing banks. Still another may labor mightily for years in pursuing pure research with no discernible result. Note the individual and subjective nature of each case. No two are alike and there is no reason to expect them to be. Each man or woman must find for himself or herself that occupation in which hard work and long hours make him or her happy.

Never worry about theory as long as the machinery does what it's supposed to do.

The Earth is just too small and fragile a basket for the human race to keep all its eggs in.

Stupidity cannot be cured with money, or through education, or by legislation.

The supreme irony of life is that hardly anyone gets out of it alive.

Humoring them costs nothing and adds to happiness in a world in which happiness is always in short supply.

The early worm deserves the bird.
