I LOVE this:
The imagination needs moodling--long, inefficient, happy idling, dawdling and puttering. These people who are always briskly doing something and as busy as waltzing mice, they have little, sharp, staccato ideas, such as: "I see where I can make an annual cut of $3.47 in my meat budget." But they have no slow, big ideas. And the fewer consoling, noble, shining, free, jovial, magnanimous ideas that come, the more nervously and desperately they rush and run from office to office and up and down stairs, thinking by action at last to make life have some warmth and meaning.
