I'm a morning person because I learned to write my novels while still practicing law. I would get to the office at 6:30 a.m. and write until other people arrived around 9. Now I still do that. I start at 6:30 or 7 and I'll write until 11 then take an hour off then work until about 2 p.m. By then my brain has had enough.
Because forgiveness is like this: a room can be dank because you have closed the windows you've closed the curtains. But the sun is shining outside and the air is fresh outside. In order to get that fresh air you have to get up and open the window and draw the curtains apart.
