Always ALWAYS ask lots of questions. Never make a decision right away. If it is a good business it is not going any where while you research it.
Get a pencil and paper ready and write your questions done. Never join, never quit asking until you get a proper answer to your questions. If you don't like the answer(s) you are getting, that's your gut talking to you.
Don't let the salesman make you feel like your the dumb one for asking. He is the dumb one that can't answer!
QUESTION: Why do they not allow questions in front of the open group so everyone gets the benefit? (All questions must be private)
ANSWER: Because questions (although they have clever scripted responses) cause people to think! And may spur more questions they can't really answer like....'Do I need to buy anything else after my 3000 buck toss of the dice?' 'How much is all that?' 'Do you have other students in the local area who have been successful and can I contact them!' That question alone would throw them into a coronary!
