Jonathan Goldstein is an audio producer and the host of Heavyweight.

“I wasn’t taking myself very seriously, initially. I liked working with my friends and family because I think I was a little more comfortable with them. Then in the second season people were writing in with real problems, and they were looking at me as a kind of expert. It was terrifying to meet with these people and see the look of hopefulness in their eyes. ... I realized I need to step it up and even if I didn’t feel like an expert—an expert in an invented field that doesn’t really exist—that I’d really have to take that on with seriousness.”
