I know exactly what I want to do, if I had the money to retire today: I'd build instruments for a living, which is something I already do as a side gig/hustle, and is something I have done for years now.

It is one of those things that fall under the category "very enjoyable, but financially difficult". If you're already set financially, living a FIRE lifestyle, you can run a shop at a scale that:

- Doesn't burn you out

- Doesn't force you to cut corners

- Keeps it somewhere between a hobby and a "job"

Me and my partner are both both chasing FIRE, and I think we should get there within 4-5 years. So-called "Fat FIRE" in 10-12, if we decide to push on. We have both our dreams of focusing on the things we care most about. We both also know very well that the things we love to do, don't pay much.
