Long-time lurker here coming out to say, yes I did. I know this sounds ridiculous, but I was watching one of Bono's speeches, and thought, "I want to go to Africa." It took some planning to sort out the logistics, but I went. Scariest thing I've ever done, as I was going by myself to a very remote place I frankly knew little about, but, as cliche as it sounds, it is indeed a life-changing experience, and I would highly recommend everyone do so. If it's not financially feasible, find a way to make it happen. After a trip to impoverished regions like in Africa, you do see the world just a little differently.
