John Warrillow is a writer, speaker and angel investor in a number of start-up companies. In this article he recounts how he realized that was wasting his time selling the wrong product. The breakthrough occurred at an executive education campus at MIT in a session by Stephen Watkins himself an entrepreneur who had sold his business around that time. Watkins told the class of entrepreneurs that they added the most value to their business in designing and starting it. After the business got going and they were still selling products and services of their business, they were wasting their time, energy and talent in the wrong direction. What they should have been doing as entrepreneurs was hire people who could sell the products and services, while they focused on marketing the company. This was how entrepreneurs could ensure the best return on their investment.
