Good luck, Bad luck or No luck?

One troubling trend amongst people today is the belief in "e;Luck"e;. If you ask "e;What is Luck?"e; giving the impression you never heard of it before they are at a loss of words to explain what exactly "e;Luck"e; is. They've never actually thought about it but just believed that it existed. First we must know what luck is before we can come to classify it, if it exists.
