Although I have a regular work schedule, I take time to go for long walks on the beach so that I can listen to what is going on inside my head. If my work isn’t going well, I lie down in the middle of a workday and gaze at the ceiling while I listen and visualize what goes on in my imagination.

I am a horse for single harness, not cut out for tandem or team work. I have never belonged wholeheartedly to country or state, to my circle of friends, or even to my own family.

The only thing that you absolutely have to know, is the location of the library.

Combinatory play seems to be the essential feature in productive thought.

That is the way to learn the most, that when you are doing something with such enjoyment that you don’t notice that the time passes.

The aim (of education) must be the training of independently acting and thinking individuals who, however, can see in the service to the community their highest life achievement.

Never regard your study as a duty, but as the enviable opportunity to learn the liberating beauty of the intellect for your own personal joy and for the profit of the community to which your later work will belong.
