Moving cities, or relationships, or jobs isn't worth as much if you aren't simultaneously working on yourself
I think there is something to be said for getting some big experiences. Moving from Pittsburgh to Cleveland might be a waste of energy. Moving from Pittsburgh to Paris is a guaranteed adventure.
I don't know if I agree or not, but it is interesting to think about.
You can obviously over-do it, and yes it probably feels good to follow the herd and stay in the "okay" relationship and the "okay" job with the same old things because you feel like that's what everyone does. But... there is much more outside that world. The walls you think are there are in fact not there at all. There is room for risk within reason in life.
