When I was sixteen, I got a summer job selling newspaper subscriptions to The Houston Post. At the time, the newspaper gave its salespeople a list of new phone numbers issued by the telephone company and told us to cold call them. It struck me as a pretty random way of approaching new business.
I soon noticed a pattern, however, based on the feedback I was getting from potential customers during these conversations. There were two kinds of people who almost always bought subscriptions to the Post: people who had just married and people who had just moved into new houses or apartments. With this in mind, I wondered, "How could you find all the people who are getting mortgages or getting married?"
After asking around, I discovered that when a couple wanted to get married, they had to go to the county courthouse and get a marriage license. They also had to provide the address to which the license would be sent. In the state of Texas, that information is public. So I hired a couple of my high school buddies and we canvassed the courthouses in the sixteen counties surrounding the Houston area, collecting the names and addresses of the newly (or soon-to-be-newly) married.
Then I found out that certain companies compiled lists of people who had applied for mortgages. These lists were ranked by the size of the mortgage. You could easily identify the people with the largest mortgages and go after those high-potential customers first (This was my first experience with what I would later call "segmenting the market," one of Dell's most significant strategies for success.). I targeted these people, creating a personalized letter and offering them a subscription to the newspaper.
By this time, summer was over and it was time to go back to high school. As important as school was, I found that it could be very disruptive to a steady income. I had worked hard to create a lucrative system and didn't want to just throw it away, so I handled the bulk of the work during the week after school, and I did the follow-up work on Saturday mornings. The subscriptions came in by the thousands.
One day, my history and economics teacher assigned us a project for which we had to file our tax returns. Based on what I had made selling newspaper subscriptions, my income was about $18,000 that year. At first, my teacher corrected me, assuming I had missed the decimal place. When she realized I hadn't, she became even more dismayed. To her surprise, I had made more money that year than she had.
