You sound like me, (also adhd). Jack of all trades.

So, novelty seeking, I do this: - work part-time on something i'm passionate about as it's products that help others. Research based, which brings more novelty naturally. Also, passion for me was the most important thing to keep my focus, not "interesting" as "interesting" gets boring. - spend rest of the time mostly building random side-projects that won't be finished, but I don't care, that's not the point.

Seems to be working well.
