Born in 1933, Willie Nelson always had music in his heart as he wrote his first song at just 7 years old. It wouldn't be until the 1950s that the singer pursued a career in country music. And as if born to be a country icon, Nelson fashioned one of the most legendary careers in the music industry. Although Nelson celebrated turning 91 back in April, he continues to perform on stage and record in the studio. Just a few days ago, he released his latest album, Last Leaf on the Tree. While not shying away from his age and the topic of dying, Nelson once shared his thoughts on death and what might await him.

Sitting down with CBS News and host Anthony Mason, Nelson discussed an array of topics surrounding his career, his legacy, and what the future might hold. But when Mason touched on the topic of death, Nelson didn't shy away. When asked what he believed happened when a person died, the singer explained, "I think we probably come back as ourselves, pretty much. I don't believe life ends, ever." Even when Mason admitted fans will always have his music, Nelson interjected, promising, "I'll be back in a minute."

Through the conversation, Nelson also opened up about his long career on stage. Continuing to perform even after taking some time off due to doctor's orders, the singer admitted to not knowing where he gets the energy. "I don't know either. I have the energy to do it and the desire."

Just like any star, Nelson is no stranger to writer's block. Although he continues to write and release songs, he noted how he struggled with writer's block. "It happens to every songwriter to a point where the well runs dry." But unlike others, Nelson found a simple trick. "Wait. I haven't written anything in a few days."

While thankful for his life, family, and career, Nelson insisted that it hasn't all been easy. While loving to perform, he said he thought about quitting every night. "I quit every night. After every tour, I say this is it. And then I get the urge again to go back."
