The next part of this chapter is talking about key application areas of using mind maps. And he steps you through making a mind map of what those areas are going to be. He's having you create a map so you can kind of make your first one with him, and then he's got you set up such that you can then expand on it as you're reading the book. Did you have an opinion on this? I thought it was kind of interesting. But i'm not going to use it for a lot of the different areas that he mentioned here.
