I've done this twice in my life. First, when I was in college, I took a semester to study abroad in china while continuing my old job for a SF startup remotely. I felt rich, yes. But it was a failure - first and foremost, I want to hang out with people whom I can communicate and enjoy my time with. I learned this lesson after trying this again, but this time, moving to India for 3 months. I am Indian, so I didn't expect the cultural barrier to be as much of a problem. It was.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
