Hr management can involve a lot data tracking. I would invest some time into bettering your computer skills. Excel can be extremely powerful in a administrative setting.

That skill set will transfer into other fields should you decide to pivot.

Check with current job to see if they will provide any training or help pay for College classes.

Wanted to re-emphasize what the last poster said. You will want a degree if you're planning to go into HR. Any kind of administration work you'll want a degree. Instead of working two jobs, work 1 job and make school (degrees, trade certificate, whatever) your second job. It's a much better investment than earning an extra $100 bucks a week.

Take it from someone who got very lucky. I got passed up for multiple leadership positions purely because I hadn't finished an undergrad degree. If my manager hadn't gone out of her way to create a position that didn't require a degree in order to pay me more I'd still be stuck at my previous cap (in a job I loved, admittedly).
