For me I just drifted there when I finished my degree and the girl I was living with at the time got a good job with Hewlett Packard. I tagged along and got a job within commuting distance. I don't really like the city I live in but I haven't bothered moving for the last 6 years through inertia I guess.
Do you live where you grew up, and are you planning on moving one day?
What keeps you living where you are
