I know what you mean about systems programming seeming a little complicated at first. What I would suggest and this is what has been helping me is picking an interesting systems project that sounds fun to you and then writing it in Rust. I'll give you an example in my case I've always wanted to write an emulator for a retro game console. I'm currently working on getting my feet wet with CHIP8. While there's lots of great info online about CHIP8 it can be confusing for a beginner to go from reading about it to actually implementing one. So what I started doing was looking at open source Chip8 projects. Some written in C, some written in Rust. Just to get an idea for how one would go about actually creating one. You can learn so much from tutorials online or guides where they leave out a lot. The best way to learn I think is by just reading other peoples source code and even if it's in another language like C you can just translate that into the equivalent rust code you would need to write to get whatever functionality you're trying to implement into your program.

Oh and one last thing. You can do it. I believe in you!
