I had a temporary change of image recently. Somehow that sensible look doesn't seem quite me, so I'm switching back to mad curly redness.
Writing in a different form or genre can sometimes feel as though what we're doing isn't quite us. I think it's good to try new styles, but not to stick with them if we're not entirely happy with the results. That would make us insecure.
Luckily the Insecure Writer's Support Group is on hand to help if that happens. Have you made any changes recently to your writing, reading or other aspects of your life? Were they changes for the better, or are you trying to grow them out?
