As somebody who has been moving every year or two since I was 10, I am trying to force myself to stay in the same city/country for at least 5 years. Being in the same location enables you to develop a social network. Most of your basic needs are already solved (housing, job, visa, friend...), and you get to spend time focusing on other issues or hobbies. Moving places is an exciting thing. But you get lots of advantages by sticking somewhere.
