Book excerpt: It's not easy to be "an inventor", but there is a market channel that can help you. Private label sales allow you to partner up with one of the major companies in your genre. You do the work, they sell the product as their own, and you benefit from sales volume you probably could never have achieved on your own. There are many factors to consider when deciding whether or not to go down that road, and the choices you make can have a tremendous impact on your ultimate goal of a sustainable system.
