How do I pick winning lottery numbers?

Ive seen some ebooks on ebay claim to show you how to pick winning lottery numbers. Ive heard that they somewhat work. Some people even write programs to pick winning lottery numbers. Anyone have advice?
Update: I don't mean like hitting the jackpot every drawing , but like how to pick numbers that will make you win a few bucks here and there.
Update 2: could i see that program please?
this is a very curious subject for me.
