Will readers remember your idea?

From the video description

Here is the seven-day memory test. Can your reader explain your core idea to another person… without opening the book? Can they draw your framework? Repeat your phrase? Use your language to describe their own problem? If not, the idea may be valuable… but it is not yet memorable. Give your thinking a name. Turn your process into three or four steps. Create a metaphor people can visualise. Because when readers begin using your language… your book stops being something they consumed. It becomes something they carry into other conversations. And that is how an idea travels without you.
