#1 it works for some people like a charm. but for others, it's as workable as a lump of sh_t. it works for some, but not for others, and for most, it doesn't.
do you like making cold calls pitching something, and changing who you are just to make a buck? I hated it after a while.
It also involves a little bit of manipulation, and you cater partly to your invites' sense of greed, ignorance, and bravado.
if it works for you, then great! if you feel that it's not for you, and it doesn't make you happy or a better person, then just drop it.
