Difference between Running Away and Moving

I went to Albuquerque this weekend - just to visit and take a break from all that represents California to me these days. It was an amazing trip.... Enjoyed myself and really remembered the person I liked to be. So much so that I sat on the plane ride home and wrote down a 3 page soliloquy that was running through my head. A short highlight on the direction of my thoughts:
An odd thought to have run through your head: Understanding there's such a vast difference between who I used to be and who I am now....

I had a conversation about how different I am today and why I make some of the decisions that I do... Specifically, why I "run away" (move!). I guess that's what it seems like since I've moved a million times in the last 3 or 4 years now. Literally, I'm working on my 14th move since October 2003... not a million, but to give myself some credit, not all of it was major moves... multiple times within cities!

Anyhow, back to the running away, which I disagree with. What's the difference between running away and challenging yourself to something new and different? Or how long are you supposed to tough a situation out before you can be deemed an idiot for keeping yourself in a bad position to begin with? I think there's a fine line between these... but I'm not one to stand still if someone's swinging a bat at my head. I will move! I think the idiot would be the one that doesn't run.... Right?

Recurring thought: Travel-Writer seems like the perfect occupation.
Reality: My writing would end up being about where my mind takes me rather than the actual places I've visited.
