When one is working out a problem ... life becomes duality. One's ego transacts the ordinary routine of things, as if the mind had an upper and lower story and the regular performance of the day's duties moved and motivated on the upper floor, while down below the all-absorbing problem toils silently, forcefully, toward its solution.

Work becomes at once a delight and a tyrant. For even when the time comes and you can relax, you hardly know how.

Perhaps nothing in all my business has helped me more than faith in my fellow man. From the very first I felt confident that I could trust the great, friendly public. So I told it quite simply what I thought, what I felt, what I was trying to do. And the response was quick, sure, and immediate.

Not only is orderliness an economy; it produces rest.

That is the wearisome part of business - there is no peace, no sense of certain, permanent achievement, no stability. The unexpected, and usually the awful, is forever happening.

a few hours with Beethoven are more restful than sleep.

I simply don't believe in failure. In itself, it doesn't exist. We create it. We make ourselves fail.
