I just want to add a point here about the travelling aspect: I am a remote developer, and I have found out that working while travelling is counter productive. When you are in a new place, you'd ideally want to spend as much time as possible exploring the place and enjoy travelling, rather than spending 8-9 hours stuck in front of your laptop trying to finish your work. I think this was the case with me because I am a full time remote employee. If you can figure out some contracts which take up 3-4 hours per day, and you can sustain yourself comfortably with that much money, you can do this. But you have to be sure you have a nice safety net. Getting stuck abroad with no money is not fun.
