Don’t copy terminal commands from internet if you don’t know what they do. Also, try new things just to try them. That’s how I started using many things that now make the core of my computer experience. Even if something looks scary I recommend giving it a go because in most cases it is much easier than it looks (at least when you have some experience with Linux).
YouTube can be a good resource at the start.
Switching to Linux was very smooth experience for me because I wanted to inform myself about Linux before switching just to know what I’m getting into. If you go prepared you probably won’t experience many problems.
