When did you feel like you were "settled" in your career? (Or do you yet??) I'm not sure that the job I have is going to be my career - right now, it's more like a job....but how long do I have to play around and try out careers?

I know that right now isn't the best time to leave a job in search of something else "just because" - but I feel like eventually I need to settle down with one job. Advice?
