Good idea - though I'll likely do this with the folks in the church where I'm located.  Starting next Sunday we have a 6-week series about living.  But we start out with asking what we would do if we got the news that we only had a few weeks to live.  Would we reach out to someone we haven't spoken to for ages?  Would there be some things we always wanted to do that we finally take the time to do?  I think it ties in nicely with the Love List idea.  I'm thinking we might take a large bulletin board type space, and have folks use whatever color of post-it note they want to put up different things on their lists.

Now, in regard to the church, the first thing I saw when reading the diagram was not the idea for a love list, but instead I saw a reason why folks don't like change in the church.  Some folks are happy with the way things are (and they likely aren't being challenged to grow as persons).  Some folks don't like the way things are, and they'd like to keep it that way because what they really like is complaining.  Only a small percentage will consider changing anything.
