Some people are happy in their coccoon. What works for them may not, and probably will not, work for others.
I've lived in 6 different states and one foreign country and probably will live in another foreign country within the next decade. I've traveled all over the US, Europe, Alaska and Ecuador. Every place I go I try and hang with the locals to see what life is really like there as opposed to a jaundiced touron view. I've enjoyed my experiences and felt its made me a better person.
