My wife and I are going to see Jerry Seinfeld perform here in our hometown tonight.

He’s set for life financially, and his reputation as one of the comedy greats is already a lock.

But he keeps touring because he loves the work.

I wrote about this previously, but I love his craftsman approach. From a 2012 New York Times profile:

For Seinfeld, whose worth Forbes estimated in 2010 to be $800 million, his touring regimen is a function not of financial necessity but rather of borderline monomania — a creative itch he can’t scratch. “I like money,” he says, “but it’s never been about the money.” Seinfeld will nurse a single joke for years, amending, abridging and reworking it incrementally, to get the thing just so. “It’s similar to calligraphy or samurai,” he says. “I want to make cricket cages. You know those Japanese cricket cages? Tiny, with the doors? That’s it for me: solitude and precision, refining a tiny thing for the sake of it.”

When he can’t tinker, he grows anxious. “If I don’t do a set in two weeks, I feel it,” he said. “I read an article a few years ago that said when you practice a sport a lot, you literally become a broadband: the nerve pathway in your brain contains a lot more information. As soon as you stop practicing, the pathway begins shrinking back down. Reading that changed my life. I used to wonder, Why am I doing these sets, getting on a stage? Don’t I know how to do this already? The answer is no. You must keep doing it. The broadband starts to narrow the moment you stop.”
