Does anyone else wish at 11:11 every time they see it?

Okay. Every time I notice the clock at 11:11, I close my eyes and make a wish. :) I do this at both AM and PM. I always wish for the same thing, thinking that if I wish for it enough, it will eventually come true.. does anyone else do this? And what's the point of wishing at 11:11 on 11/11/11? Some say, that this is a once in a lifetime thing, and I plan on wishing my hardest this day.. but why do we do it?
