This idea came from the very clever Dan Waber - and it's a blast. Essentially you make a list of 365 people who have touched your life in some way - people you have met - and then each day for a year you write 40* words about them.
Making the list, as Dan notes on his site, is the hard part. Paring down your memories about or feelings toward a person into a handful of words is the next trick, but it's actually fun.
So try it yourself. And let me know if you decide to give it a shot.

*Dan's chose 40 because the idea was to celebrate his 40th birthday. Some of us get to use a few more words. ;-)
