Be careful before you join because less than 3% make it. You will alienate friends and family.
You will ask people for huge personal favors only to screw them on their bills. The business is all about recruiting more people, period. It is going to take you YEARS before you generate residual income from the products. They will want you to attend expensive conventions 4 times a year and buy magazines and dvd's.
If you think you can put 25+ people in the business, go for it. I had 28 people under me but could not stand the lies and BS.
The owners could easily fix the issues by lowering signing up costs and making their products the cheapest in the market. Unfortunately, too many mouths to feed in this pyramid scheme.
