I think you need to answer what it is you like about your career, independent of your job. Like, I just simply love understanding problems to the point that I can identify a solution that makes it easier for everyone to understand. That's independent of my job, but I get good-enough satisfaction if my job allows me to scratch that itch.

If your job isn't allowing you to express what you love about your career, then you have something to go on in terms of changing your job. But if you're finding you actually don't love your career, that that would imply a different path entirely.
