Highly recommend Go, especially for that realm. Building something else that already exists can provide a good roadmap and reference for how things are / can be done.
You could build a server, but I'd personally find something like https://nats.io (messaging) https://fission.io (serverless) or https://redis.io (cache) more interesting. You might also look at the Kubernetes ecosystem. Building a tool or service that can interact with the API can lead to new opportunities (people hiring specifically for operator experience). I work on a code generation tool (https://github.com/hofstadter-io/hof) and https://github.com/cuelang/cue
I’ve been learning Japanese on my own for 6 years, no teachers. In the beginning I used iknow.jp which worked very well for a little more than basic kanji and vocabulary. From there I moved to Japan and messed up my study of kanji. On second year living here I started with RTK and I wish I had done that earlier. Even though I procrastinated a lot, that book has been most successful with my retention.
Now that I’m learning Korean also as a beginner I googled sentence mining and downloaded Korean deck which after 2 months of using seems to work well and now I’m at the point where I will start study of basic grammar once a week to support the anki study
Delete the mobile apps. I scrolled reddit to infinity on my phone going through news that would make me depressed. I deleted the app and have been happy ever since. I come here twice a day for 10 minutes instead and my screen time reduced by 40minutes at least. I don’t feel gloomy all the time because of news too
FWIW I did something similar. Deleted my reddit account and now just occasionally visit specific subreddits that I used to subscribe to. I find that actually going to a subreddit to find specific content I want to look at helps break the loop of endless scrolling but I still get just as informed/entertained.
