I have quite recently, but its a pretty sad story.

My best (first) friend died about a year ago, he was a film-maker and he asked me to finish his film for him - which actually meant starting the film for him as well.

Well, it took a year of obsession, and for the last month I was literally sleeping an hour or less a night, but I got it done. Now we're using it as a template for a funded project, so effectively all of my work is paying off.

Pretty extreme example, but hits the spot.
