On the rare occasion I buy a lottery ticket, I look at like entertainment. I figure i get $5-$10 worth of enjoyment out of "what would I do with $xmillions?" question. Just thinking about the exotic cars and fantasy vacations is worth the few $$. So it's almost like a movie ticket in a sense. I'm paying for a fantasy as it were.
that's how I always looked at it. two or three bucks a month in change
