This resonates with me being a product manager. In product work, honing your craft over time is what propels you and your career forward. There's no faster way to do that than working at a startup, or on a product with a burgeoning business around it.
Several months ago I took small steps towards this direction.
It started with downloading Firefox on desktop and web. I love Firefox mobile. It's performant and supports multiple tabs. Also comes in Dark Mode.
Next came email, which was difficult. I'm still transitioning. Protonmail was my pick because of the price point and ProtonCalendar (currently in beta). Gmail and Gcal are deeply integrated and wanted an alternative that could offer a similar experience. The only con here is that ProtonCalendar is web only (please support on mobile soon, Protonmail!).
Duckduckgo is a solid search alternative. Results are quality. Between these services, browsing is a joy again.
I suggest searching for documentaries on your favorite genre, whether it be Jazz, Rock, or Hip Hop. Jot down the artists/labels that pique your interest. Research those groups online.
In parallel, learning music is best when you're having fun. You should start with your favorite artists and dive deeper into their discography. Research the label they were on (fruitful if the label is independent). Look into their contemporaries. Who were those artists? Maybe they were associated with a larger movement/scene, and so on.
Finally, listen to more music! Everything (almost) is on Youtube or Spotify. Make it a point to listen to music everyday.
