Morning is often the best time to write for me, I'm usually not awake enough to get distracted.
I read something about dream journalswhich seems to be true. It was suggested that a notebbook be kept by the bed, for writing things down, even better, a tape recorder.
The reasoning was that people more often forget their dreams if they have to move around before they record them.
I find that I can write more if I start early in the day, and my thoughts are usually fresher, without the complications of style and word choice that clog my prose when I work late into the night .
Nevertheless, I still like the image of the artist working late in to the night.with a single lamp to see by.
