I'm feeling bored. My job involves linux, k8s, docker, sql etc. What should I learn next? I want to learn music but it's expensive to purchase good musical instruments. I don't like learning drawing, new foreign language etc. I like to learn programming. But I'm not sure what should I learn next.<p>Recommend anything. I don't know much about coding.<p>1) DSA<p>2) Competitive Programming<p>3) ccna<p>4) Operating System (College Course Relearn I mean)<p>5) Computer Graphics and Game Development<p>6) Do 55 DOM Projects course<p>7) CSS<p>8) ??<p>Please recommend me something to learn. It should freshen up my mind. It can take as much time it can. If you've ideas about cheap musical instruments (I hate ukulele though), do share. I can learn flute but since I follow courses, I need exactly same flute like that in course and it's expensive.

Learn to produce music. Get a copy of Reaper or your choice of DAW. Download MIDI files of your favorite older video games or classical music, etc. Get instrument plugins. Get a good set of headphones. Get a pair of monitors and a subwoofer if you can. Combine the MIDI files with instrument plugins and then learn to mix.

Learn Racket. It's an amazing introduction to computer science / programming. My partner has been picking it up lately having a lot of fun and learning a lot at the same time.
