Unlimited potential and freedom IF you have the discipline and drive to succeed. Make sure the people introducing you to ACN are making money already or you will be disappointed. Make a plan with successful mentors; follow the plan and make sure you do something daily!
Cons
You have to do the work and acquire customers and it is not for everyone. I received advise from a millionaire that people make A LOT of money either doing something people cannot do(Michael Jordan) or doing something people are not willing to do.(Make calls and network) If you cannot get by your fear DO NOT PURSUE THIS.
