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.
When I ask entrepreneurs and small business owners, it is not unusual for not having any marketing plan. I once read that Sir Richard Branson never had any marketing plan when he started the 1st Virgin business many years ago. In fact in one study of entrepreneurship (I couldn't recall the name of the study) was that as much as 50% of entrepreneurs and business owners don't have a business plan and marketing plan when they first started the business.
