I recently watched an experienced programmer build things seemingly from scratch, reason through problems clearly, and use documentation or compiler errors without needing constant tutorial guidance. It inspired me to develop that kind of understanding, but I'm still relatively early in my programming journey.
What's the best way to build a strong foundation and eventually become that independent? Should I focus on books and courses, computer science fundamentals, algorithms, open-source contributions, personal projects, or lower-level languages such as C and C++? I'm not expecting quick results—I'd rather develop good habits and genuine understanding than spend years following tutorials without learning how to solve problems myself.

There isn’t one perfect resource or language that unlocks deep knowledge. Strong programmers usually build that understanding over many years by studying different areas and repeatedly applying them. Learn the fundamentals, read books and technical documentation, examine real code, and keep making projects. A degree can provide structure and exposure to computer science, but it isn’t required if you can create that structure for yourself.
Lower-level programming can be valuable because C makes memory, data representation, compilation, and system interfaces more visible. It’s not mandatory for every programming career, though. Learn it if those fundamentals interest you or if you want to understand systems more deeply. A small compiler, interpreter, linker, or runtime can be a challenging project once you have enough experience.
Break large problems into small, testable pieces. Keep dividing a task until you can describe the next step as a simple function or operation, then implement and test that piece before moving on. This habit scales from small exercises to substantial applications and helps you reason about unfamiliar problems without needing a step-by-step tutorial.
The biggest factor is deliberate practice. Read about a concept, then write code with it instead of just watching someone else explain it. Build projects that are slightly beyond your current ability, use documentation and compiler errors as part of the process, and get comfortable being stuck for a while. That struggle is where a lot of the learning happens.
Consistency matters more than trying to study everything at once. Spend years regularly reading and writing code, experimenting, debugging, and revisiting ideas you didn’t understand the first time. You can absolutely become highly capable through self-study, although working with experienced developers can provide feedback and expose you to better design decisions faster.
It’s still useful to study good production code and compare your approach with other solutions. The goal isn’t to avoid references forever, but to try solving the problem yourself before relying on them.
