I feel extremely lucky--I landed in a career I love right out of college. I repair wind instruments for a living, and it's satisfying in quite a few ways:
>I constantly have to solve problems every day. I have decision trees that I run through, and am always refining them and establishing new ones. In the same vein, I encounter completely new problems on a regular basis, and have to solve them creatively. This is partially because I am still green (<5 years of experience), but even my mentors who have been doing this for 3-4 decades still see completely new problems fairly frequently.
>I get to help people make music. Even though my own musicianship is covered in meters of rust, I am still meaningfully involved in making music happen. Perhaps most meaningfully, I help kids play (and hopefully learn to love) music. Even though kids are often little shits who bang up really nice instruments, I want them to have as few external barriers to success as possible.
>I get to work with my hands. There's something satisfying about this that is difficult to describe. I get serious satisfaction from making something that can barely wheeze out a note into something that sings. There is definitely a fine degree of craftsmanship and aesthetic judgement that can be applied to the work, too. There are also tons of adjacent skills and bodies of knowledge that I can refine to make my work better--woodworking, metalworking, chemisty, toolmaking, the list goes on. Hell, I even plan to learn drafting and 3-D printing in the future.
Plus, scheduling is flexible and I get to play with fire and acids all day. What's not to like?
