Hi Zina,in my own knowledge the best way you do for PSA that have plan quitting from SFI is to explain them about the power of the program,there are so many ways on how to succeed in SFI. this is not a quick reach scheme. Some individuals are thinking about these, explain them that one of the single most important skills you can improve to raise your earning power is your ability to persuade.
remember the saying:STOP WISHING START DOING.
