Jim Parsons admits he spent the first nine years of The Big Bang Theory completely miserable and trapped in obsessive OCD, declaring he wouldn't repeat it for any amount of money "I was sober for nine years filming Big Bang, and I look back now and realize that at some of the best moments of my life, I was miserable. I was not happy, I was stressed, and I felt like there were so many plates I was supposed to be keeping in the air." "I thought the success and the good things happening were only due to this overworking discipline. But I made myself miserable, and I wouldn't do that again for any amount of money." "It translated in part into a work ethic, but it was really just obsessive behavior. It was kind of OCD in nature. I had a list of things in my head that I had to get done in order to be comfortable and know that I could do my job right" "And that came at the detriment of friends, family, and missing tons of life."
