While promoting his new album, William Shatner spoke to The Guardian about what it was really like during his peak fame. 

William Shatner's Star Trek Loneliness

90-year-old William Shatner is releasing a personal album that details what he learned from his time as one of the biggest celebrities in the world. He told The Guardian, "As a young actor, you're always balancing on the precipice of failure and you're about to fall all the time. And you stumble back and something comes along and it's successful, you're OK for a while and then you agonize over everything."

The Star Trek star realized that his great fame and success were not as fulfilling as many would think it was. "The album is autobiographical and one of the songs is about loneliness, how much loneliness was a part of my life."

He has come a long way since his time on the USS Enterprise as hunky "Captain James T. Kirk": "It is a part of everybody's life, no matter how much attention you get, and how happily married you are, and how many children you have. As the song says, we're all essentially alone and the big mystery is will there be anybody there at the end?"

Shatner continues to work and is starring in Senior Moment as a retired NASA test pilot who loses his driver's license! When asked why he continues to work so much he explained, "I've got a very full creative life, I'm more creative now than I've ever been. And so that aspect of my life has not slowed down."

He believes he owes his ability to continue working to "DNA, no question about it." The Star Trek star explained, "I have lived a good life. I don't do drugs, I don't drink and smoke, and I try to exercise as much as possible, with good food. My shoulder is shattered right now. I cracked the bone falling off a horse a couple of weeks ago. So my left arm is bad but I keep exercising it. It's getting better and better. But I've had the good luck of not having anything really debilitating. So nothing has sapped my energy."
