Each time that feeling hits me I don't hesitate, I just go, even if all I do is move house but remain in the same town. I've done it around 130 times. Sometimes it's been to another town, other times to another city, often to another country. It can be very therapeutic. But you must be careful you don't move away from something you have become in some way reliant upon (in a positive way that is), but haven't realised it. Make sure it is available to you in the new place.
