Book Is Up on Amazon; Now What?

Just a quick post to let folks know that my novel, The Last Good Halloween, is now up for sale on Amazon. 
For the first several hours I was fascinated by the fact that it has an Amazon best seller's ranking that seems to fluctuate pretty wildly from hour to hour. It peaked somewhere around the 14,000s. Now today it seems to have settled into the 25,000s. All of which means very little, I think, but it allows the mind to spin and spin, perhaps a bit too much.  My publisher's advice was pretty much spot on when I started emailing him frequent updates on the rankings: "At the end of the day, though, what feels best is working on something new! If we start a new project, everything else will sort itself out." 
Funny how these words seemed to calm me down. The fact is, I've been in a bit of a writing rut since the publication schedule has ramped up. There's always been something else that needed tending to before I could crack my notebook and start writing. Perhaps now that the book is finally out, I'll be able to find the mental headspace to get back to what got me here. That's the plan, anyway.
