There have been a couple of things I've been involved in launching that have been a bit more public, but I've always had other things tipping away in the background.
I've enjoyed appearing in Atlantic City. East Coast audiences are a bit brighter than Las Vegas audiences. I think most entertainers will tell you the same thing. The East Coast audiences are more perceptive - especially when it comes to a performer with a theatrical background.
One of the nice things about a second book is that your readers already have so much of the introductions on board, they don't have to put all their attention into figuring out the world and can more easily let that play out as a background to the other things you want to do.
