Do you mean you sold out in the arts or in the sense that you changed careers? If the former, I’d be curious to hear (well, read) the story since that’s not an admission one typically encounters.

I never met a professional with a conceptual category of "selling out" within the industry. Scraping together any kind of living in the arts is a massive struggle, so everyone takes "money jobs" when they can get them. During my 10 or 12 years as a working actor I had two consecutive years during which my sole income was from performing, and maybe a couple of other other five or six month periods where I was able to drop restaurant (or whatever other) gigs for a tour. This was in the early-'oughts, and I'd have to look at my social security records to be sure, but my income during those years was somewhere around $30k. I was single, and really, really good at being poor.
By the way, that's like a 98th percentile result for an actor. Most people never come close to making a living, however meagre.
There's an old, old interview (maybe Michael Parkinson? Don't remember) with Joss Ackland - a wonderful mid-twentieth century British character actor, on stage and screen - where the interviewer asks him why the hell he did some crappy science fiction film, and Ackland says something like "that was 1962? Oh, yes. Well, my mother needed a new kitchen." No actor will ever fault him for that!
What does disappoint me is seeing actors with tremendous talent who take nothing but money jobs. I get why they do it - especially for the ones at the top of the commercial heap it'd be awfully hard to say 'no' to an easy gig that comes with a boatload of cash - but I can't help but feel sad that I'll never get to see them working at their best.
Even so, my response when I see a truly bad film is generally a shrug: "a lot of actors [and associated professionals / craft services] got paid." The artists among them will learn from even that experience, and many (many many) among them will invest that income back into doing work that they believe in.
I've literally walked out of shows (as an audience member) where it's been clear that the actors are doing unsafe things, because I didn't want to see happen what you showed up to. Thanks for being there, and I hope that woman was OK.
