An intriguing question. I started using LJ in Feb of 2005. I had just completed a cross country train trip that, though I didn't know it at the time, would ignite within me a travel bug that I have been fighting to squash ever since.
quit working for Borders, which had pretty much defined my working life.
visited 25 countries, including a 6 month backpacking trip through south and central america
met people from all over the world
started living and working in Antarctica which has offered me some of the most amazing and unique experiences I can hope to have. Got to stand at the geographic south pole.
There has been little change in my personal life though. No major relationships. No children, no long term career prospects. No closer to figuring out my "passion" (but closer to realizing that passion isn't some x variable that is waiting to be solved).
