In retrospect, one good decision we made was to set clear revenue targets for those early days. In the first month we intended to make $300 in total revenue, and we did—barely. Many friends and family members were asked (okay, begged). Each month our small revenue targets increased, first to $350 and then to $400. As they rose, our struggles increased. We soon ran out of friends and family; our frustration escalated. We were making the product better every day, yet our customers’ behavior remained unchanged: they still wouldn’t use it.
