A good friend who teaches yoga told me that December was a good time to slow down and get extra sleep. I like the idea, but I also think this is a good time to stay inside and write. Of course it’s better if the weather is cold and snowy. This is the time of year to walk the floor thinking of that next scene and what will happen to the protagonist. (In case you didn’t know, I do a lot of walking when I’m figuring out what will happen next.) One also has to think about sequels, but Raymond Chandler said it best.
When in doubt, have a man come through a door with a gun in his hand.
