I have spent the last 12 months doing my own research into how network marketing works and with the power of the internet and social media how this industry has exploded but is still relatively small in NZ because of closed mindsets. Richard Branson and Robert Kiyosaki promote this way of marketing as a successful business model. Below is a link to Roberts overview on it. It goes for 14 minutes.
Network marketing is not for everyone. You have to put in the work and be committed. It is not a get rich quick scheme but it does work. I initially started this to get my favourite products for free. Then as I started to make money I decided to turn off my TV and invest that time into my mind, stretch out of my comfort zone and feel passionate about helping others to increase their income too.
