It's times like this when you need some kind of stress relief. Take a break. Go catch a movie. Spend a couple of days watching bad horror movies. Catch up with a friend. If you have pets, spend some time cuddling or go for a walk. Reinvent your sex life. Whatever it takes, do it. Just don't forget to return to writing.
I had an amazing day just chilling with my girl Michala. We talked about writing, whined our sob stories, bounced ideas off one another, ate some yummy Chinese food, and spent a good chunk of our time just talking bullshit and having a good time. It was invigorating. Actually, it was relaxing and invigorating. Relaxing because we could just forget the real world for a bit and goof off. Invigorating because we're both writers and you simply can't expect to put two writers in the same room and not have them talk through sticky plots and other writing roadblocks. I'm left feeling inspired to write, and write I shall!
You know, it's really amazing how much can be accomplished when you just let yourself take a breather. Sometimes, it takes more than just a day spent with a friend to make it all better, but if you don't step away from the situation every so often, you end up becoming a crabby recluse with no friends and enough mental issues to keep Freud busy for sixteen lifetimes. While I'm sure Freud would have a field day with that, I'd rather have friends and a life. :)
So, to all the writers out there, write write write, but don't forget to nurse your insanity lest it consumes you.
