Do you ever find your writing keeps you from sleeping?
There's so much going on inside my head that sometimes it's hard to turn it off when it comes time to sleep. It's not always writing. A lot of the time, it's every day stuff. Things I have to do. Things I should have done. But once in a while, my writing keeps me up with mental discussions about what I need to change to make it better. If I get up and write about it, I'm exhausted the next morning. If I don't, I'm likely to forget it by morning.
Guess what I usually choose? Sometimes, writing down my ideas is more important than sleep.
