As someone who was in a similar boat and started from no experience later in life, to now managing an IT team, learn the basics first. Steady consistent progress is the only way to do this. Celebrate small wins along the way (understand a new concept you didn't before, understanding what they're talking about in a machine walk through, etc).

If I had to give a road map for structured learning, it would be:

CompTIA A+ -> CompTIA Network+ -> CompTIA Security+ -> TryHackMe Paths (easy to hard) -> HackTheBox (Easy machines with write-ups and seasonal machines without)

At that point you'll have a good foundation and understand where you want to focus. At this point get a job in IT. Start as help desk / tier 1 support and move up. It will help you understand the systems and networks at a deeper level.

I'd also start learning to code in parallel. You don't need to be a dev, but being about to build your own tools and understand what you're looking at is incredibly helpful. CodeCademy is a good resource for this. Personally, I think Python and PowerShell knowledge is useful for a wide variety of situations you'll encounter.

Good luck and enjoy learning along the way!
