I have a bachelor's degree in computer science, but I'm still curious about how all kinds of things are built. A lot of programming education follows familiar projects such as calculators, websites, and small games, often through polished tutorials that provide most of the research and solutions. I'm wondering whether a better approach would be to choose random, ambitious ideas that genuinely interest me—such as a compiler, ad blocker, web browser, or AI-powered camera—and figure them out through documentation, experimentation, debugging, and independent research. Would consistently pursuing projects outside the usual learning path help me develop broader problem-solving and engineering skills, or is there a more effective way to structure this process?

Novel projects can be motivating, but unusual doesn’t automatically mean better. Common examples are often chosen because they contain useful building blocks: data structures, input validation, persistence, networking, testing, interfaces, and error handling. A stock-management example, for instance, can teach concepts that transfer to many business systems. Build things that interest you, but deliberately practice good architecture, tests, version control, and maintainable code along the way.
Be careful with the scale of some of these ideas. A commercial browser or compiler is a massive team project involving years of specialized work, but a small educational version is completely reasonable. Define a narrow first milestone, such as compiling a tiny language or displaying a few basic web pages, then expand only after that works. The important skill is learning how to reduce an intimidating idea to a sequence of manageable problems.
Yes, building things you’re genuinely curious about is a strong way to learn. Just remember that you’re not really learning how to build one isolated thing—you’re learning reusable concepts, tools, design patterns, debugging methods, and ways to break large problems into smaller ones. Try a project, read the documentation when you’re stuck, debug it yourself, and then rebuild a smaller variation without following the same guide. That loop is more valuable than simply collecting tutorials.
This approach is effective, though it may not be the fastest route to job-specific skills. The projects people commonly recommend are popular partly because those skills are in demand. If your goal is broad competence, follow your curiosity; if your goal is employment in a particular area, combine personal projects with focused study of that field. Either way, learning by repeatedly getting stuck and finding your way forward will build confidence and independence.

Exactly. The goal doesn’t have to be a production-quality browser or compiler. A deliberately limited version can teach the underlying concepts without becoming an endless project.
