For those who have done the DN thing and 'quit', when did you know?

As I approach twelve months on the road doing the DN thing, I find myself wondering how I will know it is time to settle on a single location and stay there. I’m not there yet, it may be some time before I am truly ‘over’ the DN thing, but I thought I might ask those of you who have done it and quit:

How or when did you know it was time?
