> find your target market, “start with why,” and build your “click funnel.” (“Click funnel” is a term that comes up often in online marketing speak; the basic idea is turning your existing connections into paying customers by sending them increasingly irresistible emails.)

This part is an error.

In actuality, "click funnel" refers to the SaaS product called ClickFunnels (www.clickfunnels.com), pioneered by marketer Russell Brunson.

Thanks to Brunson (and his books, Expert Secrets and DotCom Secrets), he's helped create a movement of people who aim to build their own info businesses (courses, 1-on-1 coaching, etc.).

A "funnel" is not "sending them increasingly irresistible emails." It actually refers to upselling customers. A person purchases a product (like a book) at $9.95, then on the next page, you upsell them and offer them a $97 course, then a $197 course, then a $997 live course, etc.
