As someone big on self improvement, I thought this book would be incredibly useful, particularly with its subtitle of "quicker notes, better memory, and improved learning." Who doesn't want that?
The idea of mind mapping is that it helps you organise ideas. So instead of taking notes line by line, the idea is to place the central theme or keyword in the middle of the page and add more keywords surrounding it, with lines drawn between them to represent their relationships.
According to this book (and now I know, it definitely makes sense!), mind mapping makes you more effective because this method is more compatible with the brain. This is because it matches how the brain functions biologically. Mind mapping also engages both halves of your brain at once, making you much more efficient and effective.
A key point, and one very important to me personally is that mind mapping is supposed to enhance creativity. As a writer, there are few skills which are more important! I imagine many writers would find mind mapping a very useful way of planning out their work, linking together various ideas, characters and plot points.
As the book says, it'll be difficult to break my habit of making linear notes and the mind mapping will take practice. I've only really covered how I personally will find mind mapping useful, but the book covers a wide variety of ways in which it helps people, for example; note taking, brainstorming, collaborative writing, problem resolution and more.
So if you're looking for a way to make your planning and note-taking go more smoothly and effectively, then this book is ideal.
