It's all about the wording in the advert and luck. Luck being most important and the fact you make your own luck. You just need to know wher to find the luck. I heard that the best source of luck is the rainbow, a waterfall or that cereal you used to be able to by at Safeway. That's now gone and I can't find a waterfall. The other way to get luck is make it rather than find it, this is just a little more complex than finding luck as you need to know a recepie, but you need to find this or be given it by a leprechaun and you only get those in Ireland or in that cereal you used to get at Safeway.
So I guess I'll just stick to the wording and hope for the best!
