I subletted my room in NYC for a bit more than I paid, bought a plane ticket to Goa, and started there. It was the right decision insofar as it's a very soft landing in India, which can be a fairly difficult place for a lot of people. After two weeks and some research. I moved on and spent time in a bunch of different cities in India and Nepal; most days I would simply sit and write code in whatever hostel or home stay I was at, eat cheap street food for lunch, and generally be really, really productive. When I felt like it, I'd go take a walk or see something cool in the area or take a couple days and go on a short vacation somewhere else (e.g. I would never have wanted to spend much time in Agra, but it's a short overnight trip from Jaipur to go catch the taj mahal at dawn and then explore agra fort and take a walk before getting on a bus back).
It's actually the perfect vacation -- traveling can be really stressful, always trying to get to the next place, cram in all the stuff you have to see, etc. You wind up doing crazy things like exhausting yourself taking overnight buses to save time and hostel costs. But I spaced out what could have been a 3-4 week trip across four months, and it was relaxing, productive, interesting, and fun. I got pretty well into each of my projects (all of which involved acquiring new skill sets), figured out the one that had legs and was right for me, and turned it into my next startup.
The toughest part was in Kathmandu, where at the time power cuts were 14 hours a day, and of the 10 hours with power, they were mostly at night. But it was actually nice -- I got up early every morning with a charged laptop, worked until the thing was nearly dead after the power had gone out, went to a rooftop cafe to read for a while, went back and worked/charged again for a while, went for a long walk, and got back with enough charge left to last until the power came back on.
Overall, a pretty great life.
