"Yes, My Accent is Real" by Kunal Nayyar (Atria, $26) (Simon&Schuster)

Kunal Nayyar is on one of TV’s top sitcoms, but the 34-year-old actor still doesn’t mind putting himself through hell on occasion.

At Forbes’ last check, “The Big Bang Theory” star was pulling in a sweet $800,000 an episode as painfully shy astrophysicist Raj Koothrappali.

So, yeah, here’s a news flash: He didn’t write “Yes, My Accent is Real” for the money.

“It was torture doing a book about my life,” says Nayyar by phone. “It wasn’t cathartic at all. I almost quit three times!”

Fortunately, a lot of the groundwork for the collection of essays had been laid out beforehand — the India-raised London native had kept a diary of sorts for years, scribbling various thoughts and musings on airplane napkins

So why go through the trouble of doing a book? His fans.

“Forget sales, forget best-seller lists — though don’t tell my publisher that,” Nayyar says, laughing. “When I get messages from people saying, ‘I loved your book, you inspired me to quit what I was doing or something that my parents wanted for me and live out my dreams,’ that’s a nice feeling.”
