I always tell my students to write the story all the way through, not to play with the language and fall in love with sentences that you then have to cut. I actually find that really difficult to do; there's something so demoralizing about looking at a pile of not very great sentences. As I ease into writing every morning, I tweak a sentence and then tweak a paragraph.

I've always loved short stories. Even before I was a writer I was reading short stories - there were certain writers where I just felt like they could do in a short story what so many writers needed a whole novel to do, and that was really inspiring to me. Alice Munro, I felt that way about from an early time. Grace Paley.

The stories I love the most are where the author has a lot of empathy for everyone. The author loves their characters and takes their situations really seriously, and you feel like you're just dropped into a different world.

The Israel stories were really hard for me to write, because I think that my book is very much about politics, but it isn't political. It really was important for me to not have a political agenda at all, because I have a hard time stomaching any political fiction that feels message-y.

Stuart Rojstaczer writes with enormous wit, style and empathy, and The Mathematician's Shiva is a big-hearted, rollickingly funny novel that's impossible to put down. A tremendous debut.

It's funny - for a long time, I didn't know I was writing a book. I was writing stories. For me, each story took so long and took so much out of me, that when I finished it, I was like, Oh my gosh, I feel like I've poured everything from myself into this, and then I'd get depressed for a week. And then once I was ready to write a new story, I would want to write about something that was completely different, so I would search for a totally different character with a different set of circumstances.

It was tricky [to write about Israelis], because everyone has an opinion about the Arab - Israeli conflict, and when I first started writing these stories, I was working for an Arab - Israeli human rights group. It was during the Second Intifada. It was this totally violent and intense time, and I think there's a part of me where I don't know how to write about that situation without getting my politics out of my messages, and that's something that was important for me not to do in this book.
