How often one goes to sleep troubled and full of pain, not knowing what causes the travail, and in the morning a whole new direction and clearness is there, maybe the result of the black reasoning. And again there are mornings when ecstasy bubbles in the blood, and the stomach and chest are tight and electric with joy, and nothing in the thoughts to justify it or cause it.
John Steinbeck, East of Eden
