> Yeah, I think "vanity" is not totally the right term here

“Recreation” is perhaps a good word.

But I also use “vanity” for doing serious things, for a non-serious purpose in a similar way. I.e. one day I would like to be able to afford to have some “vanity businesses”, regardless of profitability, like bar I have designed, a winery, etc.

Pretty common hobbies for the wealthy.

Those are not things that drive me, and not for appearance sake (I.e. not that kind of vanity). But if I had enough to throw in this direction without any risk to myself, I would enjoy that.
