Never run away FROM a place, run TO a place.
If you are leaving because you are unhappy, what is to say that you will not carry your unhappiness with you?
When I was young I ran away from my home town to join the Coast Guard... I took my problems with me... then after college I ran away to Alaska... when I returned my problems were still here.
I have a chance to run away again, but I'm sticking around because I feel the need to conquer this town, this set of challenges that life has thrown at me... I'm too old to run, it's time to turn and face everything, and eventuially leave with a clear head and a dream.
