I told my girlfriend at the time (now my wife) that I was leaving for Florida and was hoping she would come. It was in the works and she got pregnant and we ended up staying... Sigh...
That happened to us, except for we saved some money and just did it. We decided we didnt want to wake up ten years from now, our daughter in school and our roots firmly in the ground of a place we didnt want to be. Its easiest if your single, easier with no kids, yet still easy with a young family and shallow roots. Dont wait until its too late.
If its something you REALLY want to do, you can do it.
