Question: Does anybody knows why Seinfeld did not accept to make one more season of his show? I'm sure money wasn't the problem...
Answer: I saw an old interview with him, and he realised he was in his 40s, he didn't have a partner or kids just all this money, guess it's true what they say money can't buy happiness, I believe he just wanted a life.
Adding on to this comment, he got married in 1999. In 2014, he said, "If it wasn't for Jess and the kids, I'd really blow my brains out. Jessica saved my life. She gave me something to care about."
Answer: Seinfeld has claimed that he wanted to "go out on top". He was done with TV and wanted to venture back into stand-up comedy.
