The only thing I would do differently is try to get my expat job sooner than I did. Working in Asia isn't for everybody, but if it is for you, you can't really beat it. Anything that you could possibly want to do is no more than a short flight away. You like skiing? I've yet to find better snow than in Japan. Maybe you're a water sports enthusiast? The number of fabulous places to go to the beach, go sailing, diving, surfing, kiteboarding..etc is far too numerous to even begin to list. Maybe you like climbing/trekking? Well we have these little hills called the Himalayas nearby. Perhaps you're a city person? You like some good shopping or nightlife? Bangkok, Hong Kong, Tokyo...they make American bars look like playtime at kindergarten and the shopping options are unmatched. History and culture your thing? We're smack in the middle of most of the oldest civilizations in the world. Just about anything that you can do back home, you can do 10x more, bigger, better, or harder in Asia, and usually at a fraction of the cost.

The only thing that Asia doesn't have is...your family! So if THE most important thing in your life is living near your parents/in-laws/siblings...etc, then an expat job isn't for you. If you're happy to go visit them once a year and spend the rest of your free time doing the things I listed above, then come on over. Also if you're a person who likes things a certain way (ie the American way) then Asia probably isn't for you either. I have worked with people who love being here and people who hate it. Without fail the people who hate it fall into one of the 2 categories I just mentioned. Either they hate being away from their relatives so they spend all their free time back home and don't get to experience what Asia has to offer, or they can't adapt to the different cultures.
