I also did the same thing 25+ years ago with computer magazines. And similarly, I built up a little programing business. There, it felt like I learned a lot by experimenting hands-on. That's probably what I need to do more in this situation too. In a structured fashion. The line between being a "generalist" and "knowing a little about a lot, but not enough about anything to do anything" is fine.
