David Letterman claims that his time in showbiz made him a "worse person," and he discovered humanity living a peaceful existence in Indiana.

In the past ten years, David Letterman, who left "Late Night" in 2015, has had time to reflect on his career highs and lows.

The 77-year-old ex-late night TV host discussed the difficulties he faced in the entertainment industry and why he believes the pressures of Hollywood negatively impacted his character in a recent interview.

"Letterman admitted to GQ that in show business, he often pretended to be someone he wasn't. However, he believes that in his life in Indiana and at home with his family, he is probably the person he truly is. He regrets that these two aspects of his life don't intersect."

Letterman promptly responded when asked if his career in show business had made him a worse individual.

Yes, you're right. I believe it's because I went through show business that I can now focus on being a better person. I couldn't have reached this point if I hadn't tried to succeed in show business.

"I believe I possess more humanity now than when I was in the entertainment industry. The pressure and single-mindedness were overwhelming, and I felt like it was all my responsibility, all the time."

Letterman, who recently launched Letterman TV FAST Channel on Samsung TV Plus, admitted that he was commonly depicted as "miserable" in interviews during the '80s and '90s.

"He stated that there were a few things happening there. He admitted that he was heavily drinking during that time, which may have contributed to his misery. He also mentioned that he never achieved what he thought would be his success, like Johnny Carson, who he believed was the best at that kind of show. He felt inadequate and wondered what he was doing there."

In 2015, after hosting "Late Night" for 22 years, Letterman walked away from the show.

"Letterman's favorite part of the show was talking to people towards the end of his run. He found it tough to do comedy every night, but he was fortunate to have smart and good writers. He enjoyed talking to people the most."

But along the way, the Indiana native faced plenty of uphill battles.

"He confessed that he felt like there was an expectation to meet whenever he went out, which he couldn't fulfill. He felt like the expectation took a lot of energy, so he didn't want to drain it before or after the actual show, which was always in need of entertainment."

Currently, Letterman claims to be more content residing in his native state of Indiana.

"For 30 years, I was solely focused on my one-hour television show, but now I realize that there are other fulfilling pursuits in life and humanity has more to offer."

Despite retiring from Late Night over a decade ago, the TV host admitted he's unsure if he'll ever fully retire.

""My Next Guest Needs No Introduction" host Letterman refuted the idea of retirement, stating that it is a myth and nonsense, as he continues to host the show."

"You will never be able to retire due to the inherent human mechanism."

"As long as you are healthy, you still want to produce," he said. "And you will find ways to do so, even if I stopped doing the show, it took me a couple of years to realize that without the rhythm you're used to, it's largely unsatisfying. So, you need to find something that's important to you."
