I disagree with the age comment. If you don't want the baggage of life, then don't let the baggage build up. You can do this at any age.
I made this comment in another post also, but I will repeat it here. If you need to continue working, it's difficult to do contract work while on the move. I suggest setting up a home base in a region that you can concentrate on. For example, setup a home base in SE Asia, knock out some projects and then travel to the nearby areas while between projects. When you are happy that you have seen everything that you want to see in that region, then setup a home base in another region and repeat. With this strategy you could extend your "around the world trip" to as long as you like.
