About me
Once you have their attention, then describe the current pain they are in. If you can describe the pain of the reader you can engage them in entertaining the idea of buying the book.
You don’t need to be gratuitous here, all you need to do is be accurate: what pain is in their life? What unsolved problems do they have? Or, what unachieved aspirations grand goals do they have? Clearly and directly articulate these, in plain and simple language.
