I'm 24 and have no previous programming experience, but after trying several popular languages, C was the first one that genuinely clicked with me. I enjoy the low-level mindset and don't mind that it requires more code or makes fewer things automatic. I'm especially curious about systems programming, embedded development, and understanding how computers work under the hood, although I'm open to exploring different kinds of projects. What should I learn first, which resources are worth using, and what beginner-friendly projects would help me build a strong foundation in C?

A good next step is learning data structures and algorithms by implementing them yourself. Build linked lists, stacks, queues, hash tables, and graph searches rather than relying on ready-made abstractions. This will improve both your general programming ability and your understanding of why C requires careful memory and data management.
Don't worry about choosing the perfect specialization immediately. Work through the basics, then make several small projects and notice what keeps your interest. Embedded systems, operating-system concepts, networking, graphics, and command-line software can all be excellent ways to continue with C.
C gives you a lot of control, but that also means subtle mistakes can be hard to spot. Learn to compile with strong warning options enabled and use tools such as a debugger and memory checker. Treat warnings seriously, test your programs, and get comfortable reading compiler and runtime error messages.
You have plenty of possible directions: write a small HTTP server, make a text adventure, create a command-line utility, or explore a tiny graphics project such as a ray tracer. A free introductory computer science course that teaches C can also give you structure, while a Linux environment can help you become familiar with the compilers, tools, documentation, and system interfaces commonly used with C.
Start with a project you actually want to build. A text game, small utility, or simple hardware project can teach you much more effectively than studying syntax in isolation. For low-level development, focus on C fundamentals such as pointers, memory management, structs, debugging, and how compilation works. Once you're comfortable, try a microcontroller board and experiment with LEDs, sensors, serial communication, SPI, or I2C.
Assembly can be useful for understanding registers, stacks, and calling conventions, but it usually doesn't need to be your main focus. Most practical embedded work is still written in C, so it makes sense to build a strong C foundation first.
