The point is that doing things unusual to you is making you more clever, more open-minded, more interesting. This is common sense. No need to expand too much on this, but there is a flipside on the experiences that Derek Sivers did not talk about. When you do unusual things, when you go deep enough into another culture, you will be changed. You must leave a part of your (cultural) luggage at the door. For instance, for any Westerner, going into China for some time will change you own vision of the world, and sometime not only in a superficial way. Your political beliefs will probably be shaken (in China left is right, and right is left, compared to France). Your values will be questioned (confort, friendship, professionalism are different). What is interesting is that there will still be some invariants. Even after many years in China, I am still French. My political beliefs have changed. My values have changed. What have not changed is probably what defines me the best.
