Many people who register to distribute Amway products are taught to "buy from yourself". Of course using the products you sell is a good idea because you gain familiarity with the products and you may be able to explain and promote the products. However, one of the issues with this is some IBOs are taught to use the products exclusively without selling products to others. This makes them customers and not IBOs.
Buying products is not a business activity. A business exists to sell goods and services to customers for a profit. That's it, plain and simple. Any other activities that you engage in such as listening to a tape, attending a function or reading a book, might be educational in nature, but it is not a business related activity.
Many many IBOs are mislead by upline into thinking that simply buying their own goods is a means to succeed in Amway. One somewhat prolific but grossly mislead IBO (Tex) thinks that he can buy his way to prosperity. He is dead wrong and his results prove it.
If you are being taught to "buy from yourself", almost exclusively, you may want to step back and analyze your profit/losses and see if you are accomplishing what is shown in the "plan". IBOs who engage in the buy from yourself philosophy are basically building a product based pyramid. Keep in mind, are you a customer or an IBO?
