Or perhaps you're a lemming who follows the pack? Not saying everyone who moves out there is, but judging someone's character by their ability to change geography in the same country isn't a great idea.
Right, exactly. I moved from NY to the Valley shortly after college, mainly because I was looking for something different, and the west coast interested me. Having a thriving tech scene was just a bonus. Now I live in SF because I love it here. If I really wanted to, I could be just as successful back east. I endure the high cost of living because I like the area, not because I'm driven or ambitious or something (which I am, sometimes... and sometimes not).
