One chapter could be worth 10 lacs

From the video description

A high-value chapter usually does three things. It solves an expensive problem. It contains a repeatable method. And it can produce a measurable result. That is the hidden value inside a strategic book. You are not only writing pages. You are creating intellectual assets. So look at your outline and ask: “Which chapter could become a complete solution on its own?” That may be the chapter that builds your next revenue stream.
