I forget where I found this one, but there's a site called 43Things.com that allows you to share your life goals and examine others'. It's a social thing, like del.icio.us or parts of flickr.com, in that it allows you to tag (i.e. categorize) your goals, and add someone else's goal to your list.
It also lets you indicate that you've done a thing, and post whether you think it's worth it or not, and why.
Some of the items are silly ("Have 43 things on 43things.com"), some are pretty expectable ("play guitar"), some are opinionated ("witness the end of IE"), some are general ("get rich"), and so on.
I'm having some doubts as to whether or not it's a useful site (like del.icio.us and flickr.com), but it's fun, just the same. FWIW, my list is here.
