Matthew Perry: I'm Jaded But My New Show Makes Me Happy

But the former Friends star, whose new NBC comedy Go On premieres Tuesday night, can't help smiling when he talks about his new costars.
"I'm jaded because I'm old, but these guys are literally singing all day long and having a good time," Perry, 43, tells PEOPLE. "Everybody is really funny and really smart and really happy to be there. We all know that we're a part of something that is at least is aspiring to be cool and different."
Perry plays Ryan King, a fast-talking sports radio host who, after a period of struggling with his wife's death, begins group therapy.
The role is right up his alley not only because he's a sports fan but also because, he jokes, "It's not foreign for me to be talking about my problems in circles."
"In group therapy the premise of it is that you're not alone and that's what my character has to learn – that people need people," says Perry, who's been open about addiction recovery in the past. "Unfortunately for him, he needs this wacky group of people."
Whether the show is a hit or miss with viewers, one thing Perry says he's learned to do is not put pressure on himself.
"The only pressure I feel is to have fun and try to put on as good a product as we can," Perry says. "I learned a long time ago to not be invested in any kind of results."
Besides, he adds, "I've been on a show before where I was on a billboard and then after like three or four weeks they took the billboard down and replaced it with nothing. Took my face down and put a white board up. So I don't get too attached to these things."
