Reminds me of a couple of married friends of mine. The wife played a classical musical instrument (e.g., not an electric guitar) and had her sights set on being a professional. While working towards that she did a lot of teaching/practising/etc, and her students would often say something along the lines of "I'm so envious of all this time you have to practice music! How are you able to do it?!" and her reply was always a bit of a let-down/reality check for them: "my husband works in tech."
Not quite independently wealthy, but I imagine there's a fair few artists out there in a similar position.
