I can identify with this. I've founded a gamedev company, taught Computer Graphics, and worked at Google and Improbable as a SWE; but in the middle of all this I wrote a novel, I recently quit my job to become an actor/filmmaker (https://www.imdb.com/title/tt10232800), and I really enjoy making Italian goodies on my free time (mostly biscotti, tiramisu, and limoncello). I'm also thinking of learning bookbinding / restoration, and how to draw and paint.
I can't tell whether I'm "doing this right" -- and by "this", I mean "life". Sometimes I feel like I'm half-assing everything, and that I'd be better off laser-focusing on a single thing. Some of my friends have, and they're further along their careers (are they happier? I don't know). Sometimes I feel life is too short to not do what I feel passionate about.
I'm 38 and I'm doing OK in life, but I feel like I haven't figured out what to optimise for. I have this lingering feeling that I could, and should, be doing better (for some vague definition of "better").
Sorry to bring a personal question to HN, but the article made me think about my situation, I can't think of a better crowd to get their opinion than this one.
