Henry Miller said this quote

“ This was the sort of ebullience and élan I prayed for when I felt the desire to write. I used to sit down and wait for this to happen. But it never did happen- not this way. It happened afterwards, sometimes when I had left the machine and gone for a walk. Yes, suddenly it would come on, like an attack, pell-mell, from every direction, a veritable inundation, an avalanche- and there I was, helpless, miles away from the typewriter, not a piece of paper in my pocket. ”
