6. SELL A PHYSICAL PRODUCT Go search Amazon under books for “lose weight” or “eat paleo.” You’ll see thousands of books, and a lot of them are essentially buy- er’s guides for physical products like supplements, food companies, or one-off products. Mark Sisson is one of the best in this space. He started Primal Blue- print and has published nearly a dozen books about his version of the paleo diet. They’re great books. He sells them on Amazon, and even gives many of them away on his site. Not only do they help people eat right, but Mark also has a com- plete line of Primal Blueprint supplements and food that people can buy. They don’t have to buy these products, but they’re there and easy to purchase, and the books and products dovetail perfectly. Think about it—would you respond to an ad about supplements? Probably not. What about a book that teaches you what supplements to take, when, and why? If you trust the book, you’ll trust the supplement recommendations. Mark has great books on eating that you can trust, which automat- ically gives his supplement recommendations more credibility. 7.
