I disagree with everyone that is disagreeing with this business model. First off, network marketing or multi-level marketing systems are not pyramid schemes. Pyramids are illegal and don't involve actually selling a "PRODUCT". The whole world is based on network marketing system...it's just that nobody recognizes that(every company recruits when they hire employees) and somebody is ALWAYS at the top making more money than someone else.
Take Walmart for example- The owner, president, ceo, managers, supervisors and finally employees make up the company....who is earning more? Obviously the people at the TOP!
Joining a network company involves a lot of hard work and you have to be strong with an open mindset. You will be rejected by hundreds of people and you have to be able to conquer the rejection and keep on going to achieve your goals! It can be done but with a little more than 15 hours a week though, you can probably make a few hundred dollars in 15 hours a week but if you want to climb the ladder to earn 30/month you have to put in the effort. Everything in life requires effort, nothing comes for free! Once you get the system working for you then you earn residual income but this will take anywhere from 5 to 10 years!
They provide excellent training and will change your life as you know it if you BELIEVE in yourself!
If you lose friends over this than were they really your friends to begin with? Don't let negative naysayers stop you from achieving your goals and dreams, trading time for money in a job will never make you rich...but believing in a proven system that works(IF YOU FOLLOW THE SYSTEM) will!
Good Luck!
