Yeah see the thing is, the way I see it is you can flounder (and waste precious time) or you can just pick something and run with it. It's not terribly easy to change career paths but make the best out of what you are doing in the meantime and figure the rest out as you go along. Just don't take coursework you loathe. The courses I took were quite difficult, but at the same time they were intriguing. If I had hated it, I would never have continued. I have held so many different jobs in my life and I plan on doing other things in the future once the kids get older.
SWMBO gets first crack at more education though, she dropped college because she couldn't decide. Fortunately, it's worked out well for us, but tbh she still bounces around on "what she wants to be when she grows up". My point being is that if she had stuck with it, at least she could have had built up accreditation in a field. Most of that stuff is the basis for getting a degree in just about anything. And once you get a degree it is even easier to pick up in a similar field.
I have found first instincts are often quite a good gauge. When I first started into college (back when I graduated HS) I was undeclared. Out of the blue I picked Agricultural Engineering because my advisor told me I had to pick a major. Well I dropped out because I just didn't have direction (as a person) in my life at that time. Fast forward to when I was 24, I went to school with a wife and child in tow, with EE (and another degree in Physics) as a goal.
I don't really do much EE stuff, in fact it's a mix of ME, CompE, Computer Science, Physics, Data Analysis...I fall back on the EE for signal processing and such. One of my favorite things to do is growing food. Not saying I would have been happy as an Agricultural Engineer, all I am saying is that your 'loves' are already there. You can't go by the 'undiscovered country' in your life because there are infinite lifetimes of things you can do out there. You just have to find a way of whittling down to what will bring you satisfaction.
I think I need a beer after writing all that. I suspect you'll need a beer too when your done reading it
