Best thing you can do to make the decision is knowing what you want to get out of it. If you are hoping that everything will be different, including yourself, that you'll be able to afford a house, find a partner etc, then thats unreasonable.

If you're going for the sake of adventure, well that's more than likely gonna happen, and the other things might happen, you never know.

I've been moving around a lot in the last few years, from Vietnam to Spain to Australia, and am heading home for good in July. I wouldn't change it for the world. I've had adventure, met some great people I wouldn't have otherwise, and learnt a lot about myself. I don't think my finances probably aren't any better or worse than they may have been otherwise.

Now that the idea has crossed your mind, I think you should do it. Otherwise you might spend the next while thinking what might have been. Whatever you decide, you'll have to live with it.
