I can say from my own example:PSAs is most valuable members for us.Because we have earnings from them on SFI and from theirs buyings on TripleClicks.I am ofering TripleClicks memebership only to people who don't have i time to work.In SFI is the best that you can ear quick money,but I think that is not smart to think about quick success.We need to build a team of workers and make second income for future time.Just be patient and money will come.
