It's 4 weeks before Xmas, it's not quite payday. People just don't have the money to splash out on luxuries (us). Cams/phones are dead too.
You need to take this time to update ads, write a blog post, find new places to advertise, update your photos, look for new lingerie/outfits/toys. Lots of things that could be spending your time more wisely than worrying about a slow few days.
And - if you haven't already - start saving. When you have a run of lots of bookings/income, save as much of it as you can. Then a slow few days won't worry or hurt you.
