If you like to work with your hands and have space, build something physical: big and complex, and actually finish it. I built a single engine two seat kit airplane in my garage, did all the flight testing, and now have an interesting way to travel/commute as a result. The "finish it" part is the most important bit. Computer people spend too much time working on projects that don't have a "done" state. Change that up.
I would start smaller though. There are a lot of half finished airplanes (where the last 20% takes 80% of the time...) and the maker is dead.
I've been working on a ukulele for over a year now and it isn't close to done yet, and this is a much smaller project. (Or maybe I should say I've been working on raising kids for a decade and there is another left?).
