Maybe it’s just a sign of the aging of the Baby Boom generation, but it seems like everybody nowadays is supposed to be making a Bucket List and checking things off it. Books about the top hundred (or thousand) things that you should do or places that you should go before you die are all over the best-seller lists. But what happens when you end up liking something that you’ve already checked off so much that you want to go back and do it again and again? That could get seriously in the way of working through the rest of the list.
