Five years in, you'll have a huge pile of cash and an insane chunk on your resume that will almost certainly guarantee you an interview wherever you want. Once you hit that point, take some time off and do literally anything. Start a startup, be a contractor, get a new degree.
You have stumbled onto the sort of prosperity (easy low-stress job) that 99.95% of the world literally dreams about. To throw it away because you're not "creatively expressing yourself" would be foolish.
This advice doesn't apply if you're a relentlessly competitive founder type like Gates or Bezons, but if you were of that mentality, I doubt you'd be having the same troubles you are.
