I have several author/friends who were greatly affected by the B&N/S&S debacle. On the order of thousands of copies. Me, B&N has done very little for me, so it would just be business as usual.
I've gotten most of my sales through Amazon, indies and libraries.
Rick, I think you can write off the portion of your mortgage/rent that applies to your home office. As others have mentioned, also, books, trips for research, conferences.
(((Caleb))) Get some rest and deal with everything after some shut eye.
What Rick said, Caleb. Hang in there...
Jealousy -- hell, yeah. There's always another rung up that ladder where you wish you were. I'd like to be on the one where I make enough dough for a decent place to live. I'd like more critical attention. That kind of thing. But you can only spend so much time obsessing on those things. It's a huge cliché, but comparing yourself to others is a sure way to be unhappy...
