I've never had WiFi at home. I'm too easily distracted, and YouTube is too tempting.

But you know, there's something about the kids finishing their homework in a given day, working one-on-one, getting all this attention - they go home, they're finished. They don't stall, they don't do their homework in front of the TV.

It was just an idea I had, that it could be cool to have a book covered in fake fur.

And that's actually the brunt of what we do is, people going straight from their workplace, straight from home, straight into the classroom and working directly with the students. So then we're able to work with thousands and thousands more students.

Every time I get through the work on a book of nonfiction, I say I'll never do it again; it takes so much out of you.

I laugh and joke, but I don't get distracted very easily.
