Willie is keeping busy.
Texas Monthly asks Why Does Willie Nelson Still Do It?:
“I think I need to keep being creative, not to prove anything but because it makes me happy just to do it,” Willie says. He partially credits doing what he loves for keeping him animate into his eighties. “I think trying to be creative, keeping busy, has a lot to do with keeping you alive.”
It’s important to have something creative to work on, whether it’s part of your career or a side project. You have to keep the brain moving and thinking.
