beginner's luck, please?

I'm going to Kentucky today to buy party supplies. My husband asked that while I am there I purchase a powerball. I didn't ask, but I'm pretty sure that is a reference to the Kentucky lottery. I have never bought a lottery ticket before. It's always seemed like a foolish waste of money. But I am also not a gambler. So, I'm wondering: do people ever have beginner's luck with lottery tickets? Don't the winners usually buy scads of tickets? Well, I promised I'd buy one, so we'll see. I don't think I like the idea of walking around with unrealistic expectations, or setting myself up for disappointment. So, I plan to stay detached from the process, without actually losing the ticket. Wish me luck?
