Most people that start a venture in network marketing do not succeed. I am not trying to start off with bad news it is just a fact of the business. I personally believe that one of the main reasons that most people fail is that they never took the time to develop an MLM marketing plan. This is actually true of just about all business models.
What was the outcome? As much as 90% businesses started by entrepreneurs and small business went busted or failed within a year. I experienced one of the many busts few years ago (with my cafe business) because i don't really have a proper and "the few solid sheets" called a marketing plan.
