This is the first and only career I've had. I did the housewife thing for years, and now I'm in college. I'll graduate with my first degree at age 41.
My job sounds incredibly boring. But I find it fascinating, challenging, and rewarding. (I'm an accountant for an insurance company.) When I learn all of this stuff, I'll move on, or up, or both. LOL! The biggest thing to me is to be able to use various skills (or moods, depending on how you call it) and to be constantly challenged. My mind requires "food" - it's a fault, I know. (wry grin)
So, for you I'd say that you need to find whatever it is inside you that makes a job wonderful. What are your basic needs?
Then I'd go and talk with people working in the fields you're drawn to. See what they have to say about it, and think hard on how that fits you.
And then, once I've chosen a path, I'd follow it with all my heart. If it turns out to be something different later on, that's ok. If you've enjoyed the time and feel a sense of accomplishment, what else matters?

We are what we repeatedly do. Excellence, then, is not an act but a habit.
