I've become increasingly interested in computers and programming. I know some Python and am continuing to learn, but the field feels enormous. I'm curious about game development, cybersecurity, Linux, and understanding how computers and software work in general, so I'm having trouble deciding what to focus on.
I don't want to spend all my time watching tutorials or taking courses without building anything. I want to make projects, understand how they work, solve problems independently, and eventually create something real that could lead to future opportunities.
If you were advising someone with basic Python knowledge, what would you suggest learning next? Are there particular projects, fundamentals, or resources that would help me choose a direction while developing practical skills? I'd especially appreciate advice from people who remember what it was like to be a beginner and learned how to stop jumping between topics.

Use tutorials and courses to learn fundamentals, but rely on documentation when you’re actually building. Pick a manageable project, try to implement each feature yourself, and look up the official documentation when you get stuck. That process teaches you how to solve problems without needing a step-by-step guide every time.
A structured introductory computer science course can give you a useful foundation, especially in algorithms, memory, programming concepts, and basic systems. You don’t necessarily need to commit to a full degree before building things, though. Combine structured study with projects so you gain both theory and practical experience.
Don’t worry about choosing a specialization immediately. Most areas share the same foundation, and building projects is the best way to discover what you actually enjoy. Since you know some Python, pick a project that seems slightly beyond your current ability—maybe a command-line password manager, file search tool, simple HTTP server, socket application, or small game. Aim to understand most of it, then research the rest as you go.
Use Git, separate environments, documentation, logging, error handling, tests, and a README so you learn to build software rather than just isolated scripts. Also study data structures, algorithms, complexity, memory, processes and threads, filesystems, networking, and operating-system basics. Learning some C later can help make concepts like pointers, memory, compilation, and linking less mysterious.
Once you have some projects, branch toward whatever interests you most: web development involves HTTP, databases, APIs, and JavaScript or TypeScript; cybersecurity benefits from Linux, networking, C, operating systems, and assembly; game development may lead to C#, C++, graphics, and linear algebra; systems work often involves C or C++, concurrency, and operating systems. A broad fundamentals course can be useful, but spend considerably more time building than watching tutorials. You learn programming by repeatedly encountering problems, reading documentation, debugging, and finishing things.
Finishing projects matters a lot too. The final stretch—handling edge cases, cleaning up the code, and making it usable—is where you learn things tutorials usually skip.
