I think, aside from major culture changes, location has very little to do with sameness. New v. different realtes more to the kinds of lifestyles and how you spend your mundane moments.
Why don't you shake up your mundane moments? Start coming up with a feasible gameplan where you can throw yourself into a new foreign situation where you have to adapt and grow and learn. Can you make your job part time while you try a new side job (that you've sold to your current employer as "career building skills I can bring back to the team here")?
