Two years ago, I went one step further and moved from SF Bay area to Saigon, Vietnam. I've had a variety of tech jobs while here, but I am currently consulting for two primarily US based companies.
My expenses are almost nil (compared with before) and I live a very minimal lifestyle (own and purchase very little). I plan on going nomadic in the next couple months (I've never been technically homeless) and driving a motorbike around Vietnam, Cambodia and wherever else I want. I can work during the week and travel on the weekends.
I'm so much happier with my life. I was doing it wrong before.
