(For those of you who don't want to click the second link, here's the money shot:
List the ten most expensive things (products, services, or experiences) that you have ever paid for (including houses, cars, university degrees, marriage ceremonies, divorce settlements, and taxes). Then, list the ten items that you have ever bought that gave you the most happiness. Count how many items appear on both lists. )
