If you're trying to get stuff done though, I think a good strategy is to pick a place and stay there for a few months, rather than being 'on the road' and traveling around from place to place. You can still be 'location independent' by renting an apartment for 3 months in a foreign country (like the Costa Rica example that was on HN a few weeks ago). But at least then you'll have more of a sense of routine, waking up in the same place every day, and because you have a full 3 months to explore the place, you won't feel as obligated to rush out and see the sights all the time.
It also really helps to be able to set yourself up in an office with an ergonomic chair, external monitors, and proper mouse/keyboard. That might be a bit more difficult to do if you're in a foreign country, but you can definitely buy used and sell again when you leave.
