Why Jim Parsons Was “Miserable” During Big Bang Theory Fame

And if Parsons—who starred on The Big Bang Theory from 2007 to 2019—was given the opportunity now, he said he “wouldn’t do that again” and not “for any amount of money.”

“It was stressful and miserable at times,” he admitted. “I made myself miserable.”

While the Hollywood star noted that his behavior partially “translated” into a dedicated work ethic, there was a larger inner battle at play.

“It was really just obsessive behavior basically,” Parsons told podcast host Jon Dean. “Yes, I was disciplined. Yes, I had a good work ethic, but a lot of it was because it was kind of OCD in nature.”

As he recalled, “I had a list of things basically in my head that I had to get done in order to be comfortable and know that I could do my job right, which I don’t think was true.”

And Parsons admitted his behavior negatively impacted his personal life, sharing, “I missed tons of life.”
