The news that Princeton is creating a program so that incoming students can spend a year doing social work abroad made me deeply envious. As someone who has never taken more than two weeks off at a time since graduating from college (and I've taken all of two two-week vacations), I wish I'd spent some time getting a better sense of who I am and what the world is like. I do wonder, though, if 18-year-olds are ready for the experience; personally, I'd have been better off taking the year after college, not before it. Got any advice for any students thinking about one? And what would you do with a gap year?
