I just went to the Toronto Star website (thestar.com) and found this link to a really great blog that talks about all the awesome things that can happen/have happened. It's called "1000 Awesome Things" and currently is at #772. The blog has had over 3 000 000 hits and just won the 2009 Webby award.
Personally, I think "1000 Awesome Things" could work as a great remedy for sadness. Whether you're in the plainest suburb, the busiest city, or the lonesomest countryside, I assure you that most of the awesome things written about have happened to you before.
