The best piece of advice I ever received about being a writer came from my brother Lee. I was just starting out and he told me that if I wanted to have a long career, I had to be versatile, that I shouldn't just think of myself in one way, because there would come a time when maybe that one thing wasn't working out for me - and I'd still want to earn a living as a writer.

My god, people are selling their work and people are reading it! The horror! That MFA programs have to advertise that they'll let you write YA or fantasy or what-have-you is just absurd, but we do, because the presumption is that they're closed to that sort of thing. You're offering an MFA in creative writing? Teach people how to write well, worry about that part, let the writers come up with the stories.

The fact is, though, what I think we really like is Marlon Brando, Al Pacino, Robert De Niro and James Gandolfini. We like what the media has created of the mob bosses in movies and TV and books, because it's something the average person never comes into contact with, it's almost as outwardly outlandish as a sexy vampire, and so we can romanticize it, it's non-threatening.

I was aware that I had to pay off things in a convincing emotional fashion, that I had to address the lingering plot points in some real tangible sense, and that I had to make this a self-contained novel, in case I'm run over by a bus tomorrow or in case there's no demand for anyone to ever see a sequel. (Two things that I hope don't happen, incidentally.)

I was thinking a lot about the aftermath of bad choices, how people deal with the trauma of having survived trauma, if that makes sense, and so I wrote about this character's last day on the job, how after spending 15 years pretending to be a rabbi, he'd in effect become a rabbi.

I think my philosophy has evolved over the years. I started teaching almost 15 years ago and I've learned that how one student learns is obviously much different than how another student learns and so I've had to figure out how to get through to people honestly without hurting their feelings - which is no easy task just in the scope of being a human being, much less in the classroom, but which is something that is more important to me now than it was when I was 30 - and to show them a path to improving.

You don't see Los Angeles erecting a museum dedicated to the birth place of the Crips and the Bloods and the Mexican Mafia, with a special guided bus tour highlighting the rise of the crack trade, yet you can hop on a bus in Chicago tomorrow to see the famous locales of murders. I have to imagine there's some wonderful academic book on the sociology of this out there.
