It's not what people look like so much as how you find them. Selling a product requires three things:

1. Having a product to sell.
2. Having a group of people who would want to buy your product.
3. Communicating your product to that specific group of people.

The trick is finding them to communicate. You can't do that until you first know who they are, and then know how to find them.
