I'm 21, have a degree, and want to land my first IT or software-related job, but I'm overwhelmed by the number of things people say I should learn: Git, Linux, Docker, APIs, cloud platforms, data structures, AI, security, and more. Every topic seems to lead to several others, so I'm not sure what deserves my attention first or whether I'm already behind.
I'm less interested in memorizing specific technologies and more curious about how experienced developers think. They seem able to break large problems into smaller ones, recognize patterns, debug effectively, understand dependencies and constraints, and learn unfamiliar tools quickly.
Does deliberately practicing programming, solving problems, debugging, building projects, and exploring different technologies actually change the way you think over time? If you were starting again at 21 and wanted to become employable, what would you practice to improve your ability to learn, reason, and solve problems rather than simply collect technologies?

Experienced developers usually aren’t memorizing every tool or its syntax. They build a library of recurring problem shapes: caching, queues, race conditions, data modeling, authentication, and so on. Once you recognize the kind of problem you’re facing, you can look up the specific technology or syntax needed to solve it. Build projects and use the challenges they create to guide what you learn next.
Use real job listings to choose a starting direction instead of trying to study the entire industry. Look for entry-level roles, identify the repeated requirements, and practice those through small projects. You don’t need to be an expert in everything; it’s better to become dependable in one useful area while building a broad foundation.
I think I’ve been overthinking this by trying to learn everything at once. I’ll focus on the requirements for actual entry-level roles and build from there.
Constant change is part of the profession, not a sign that you’re failing. Experienced people still learn new systems and technologies regularly; they just have more fundamentals and past experience to connect them to. Get comfortable being a beginner in a new area, keep building, and let each project expand your mental models.
The improvement happens gradually through repetition. With enough practice, you get better at breaking tasks down, debugging, spotting patterns, and figuring out what information you’re missing. You’ll still encounter new tools every week—even after many years—but the unfamiliarity becomes less intimidating because you’ve learned how to learn.

That changes how I was looking at it. I assumed experienced developers remembered huge amounts of technology, but learning to recognize problem types makes much more sense.
