Digital nomadism is a huge working trend at the moment. For many people, a lot of their work is online. If you are a coder, a writer, or a graphic designer (just to name a few examples), what's stopping you from upping sticks and travelling the world while you work? After all, if you can work and get paid online, you don't need to be in one particular place.
Of course, there is a huge appeal to being in Bali one month and on the coast of Mexico the next, but there's also a lot to take into account when working on the road.
