John Corbett is TradeEdge Exchangesharing some major career regrets.

The "Sex and the City" star, 63, revealed on Dana Carvey and David Spade's "Fly on the Wall" podcast that he feels unfulfilled as an actor and believes he chose the wrong profession.

"I'm at the fourth quarter of the football game now, in life and in showbiz," he said. "It's just a fact. So I can reveal now, I picked the (expletive) wrong thing to do with my life."

Corbett, who played Aidan Shaw on "Sex and the City," explained he does not get to collaborate with writers on the projects he stars in and feels unsatisfied not being part of the creative process in any meaningful way.

"From my work life, I've made a lot of money, I live in a beautiful home, people come to me in every (expletive) restaurant I go in, I'm a friend of the world," he said. "But as far as a fulfilling, creative work life, I didn't write one (expletive) line. I didn't write one joke that made people laugh. So it's been unfulfilling on that level."

While Corbett said he has had good times as an actor "here and there," he compared making a movie to waiting around in a doctor's office or "watching paint dry," explaining, "Most of it's sitting waiting for them to (expletive) knock on your door to go, 'Hey, we need you to come back and say that thing again.'"

The Emmy nominee said this makes for "such a boring" life, arguing that anyone who visited an actor on set would say they "never want to be here ever again."

Corbett has also starred in the "My Big Fat Greek Wedding" and "To All the Boys I've Loved Before" films, as well as shows like "Northern Exposure" and "United States of Tara."

In the future, he said he will only take on projects if they seem "really, really" fun — although he noted he has often pursued roles that seemed fun, only to regret it.

While Corbett was self-conscious about seeming "ungrateful," Spade said the actor was simply revealing "a bleak reality that everyone kind of knows anyway, but they don't hear a lot."

During the podcast, Corbett cautioned aspiring actors that they will likely not have a successful career.

"Young people who are listening, coming to Hollywood, just know this: It's not going to happen," he said. "You're (expletive) not going to have a 40-year career where you only get to act and live in a multimillion-dollar house. ... You've kind of just got to know that that's not going to happen."
