[Max Planck] was one of the finest people I have ever known... but he really didn't understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood [general relativity], he would have gone to bed the way I did

On the other hand, 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.
