Ask HN: How to thrive as a self-taught developer?
I'm looking for advice, opinions, or stories of similar experiences regarding where I am at personally both from a career, and personal development, perspective. In brief, I am a "self-taught" developer working a comfortable job that is not stimulating who is plauged by decision paralysis on what are valuable next pursuits.
I entered the software development world three years ago after being offered an opportunity to "Learn on the job" from a colleague. This ended up being a fantastic opportunity for me as it both increased by quality of life through increased compensation, but more notably, I felt massively inspired by all I did not know, and massively accomplished when pushing a feature to production. During this time I went on a learning rampage which resulted in both further career success (promotion) and a desire to write personal programs for hobby. I was hooked.
It's worth noting that the career success is possible not because I was some sleeper pro developer, but rather because the team I was moved onto had some code/product quality issues already, and hard work was eagerly rewarded, so I stood out. In fact, I'd still consider myself a pretty sub-par developer, at least by HN standards (more on this fallacy in a moment).
While it was great to learn on the job, I also learned how much I was _missing_. I do not have a computer science degree, and suddenly, the inadequacy perception crept in. I don't have a public portfolio of fantastic problems I've solved or products I've built. I don't have a score of one trillion on leetcode. I hadn't yet sold my first SaaS startup to Peter Thiel who then shook my hand firmly. I believed I must take immediate action to remedy these shortcomings.
This is where we land currently. A JVM developer who day in and day out at $BIG_COMPANY makes minor changes to SpringBoot REST APIs and does not currently have a plan for self improvement as it could be called. I know a single programming language with a below-expert-about-mid-high level of competency. I'm constantly thinking about various directions I could move in, including learning a new programming language, honing my current language skills to expert, improving my academic side (i.e. taking online courses on math, comp sci, reading SICP), working on some personal project, and more. The underlying issue that arises from choosing one of these pursuits is a tree of desicions to be made which ultimately results in paralysis.
I'd appreaciate any and all input/commentary. Likely best to focus on what I can do outside of work as it's not currently feasible for me to change jobs.
