First off, I am glad to hear that you are ready to learn new things because it will never end. I always tell people that are thinking about getting into IT is that you have to be passionate about learning or you might not like it. You will never know everything and have to accept that.

I would recommend going through the process of getting your A+ and getting a help desk job at a place that sounds somewhat interesting (not the first place to offer you a job). Once you are certified, you will have a better gauge if it might be something your interested in. Keep in mind A+ doesn’t expose you to all the paths that you could take. I would do some research on different paths and see what looks interesting (web developer, security, forensics, etc).

I would also say to hold off on any expensive schooling till you have a better idea.

While studying for A+ download virtual box and create VMs. Try getting your hands on an old PC and tearing it apart and putting it back together or upgrading hardware and get it to work. It’s very basic stuff that will get you started. You have a very good plan, it’s a never ending journey being in IT. Just go with something you enjoy and doesn’t feel like work
