I'm reminded of two things: (1) XKCD's IRC channel, which had a bot that kicked you (with an exponential timeout) if you ever repeated something someone else had said before. I think the idea was to encourage originality. (I suspect it actually encouraged strings of random numbers on the end of sentences). (2) Finding the perfect journal - the right cover, weight of paper, lines, everything - then never writing in it because it's too good to write in. "You only get one chance at this" is a high bar to clear. I like it, though.
