Yep, I write out rough drafts in a composition notebook, writing comments and notes on the side, and then rewrite in on the computer. Rough drafts are to get the creative juices flowing. I'll worry about perfecting it later on the computer.
I find it interesting that my writing is so much better when I'm tired than when I'm well rested. For instance, I've been trying to write one specific scene for almost a week now and never could get it. Now, just a little while ago, I sit down and get the whole thing done in half an hour. I just finished a few minutes ago. Maybe I'll start writing more late at night.
I work best well rested, but late at night. Luckily, my schedule permits me to stay up all hours of the night, so yeah, I'm covered. lol. I write best around midnight, when the house is quiet, and I am not yet in need of sleep. It's wonderful
