I’m not kidding.
Write when you’re sad, it’s when the best poetry comes out, often.
Write when you’re angry… you’ll be surprised how much you get done rage writing… though you may have a lot of editing to do.
Write when you’re frustrated, it’s therapeutic to take out your frustrations on your characters who have done nothing wrong to you.
Yes, write in most situation and it will be fine… but not when you’re sick. Last week, I came down with a bad fever and couldn’t get out of bed. So I went to work on a story that I’ve been slowly writing over a while. Page after page appeared and I was thrilled. I got a lot more done than I thought I could.
Then I came back and re-read what I wrote… and had to completely undo everything. Seriously, half of it was complete gibberish. So yeah, no writing when your sick. It will take you to weird places…
