I never got the book because as soon as I heard about GTD, I was sold. I immediately went and read gads of info online about it, and started applying what I learned immediately.

I sort of planned to get the book eventually. And when I decided to introduce GTD to the group, I went to the library, but the book was checked out.

I found GTD pretty simple to pick up, but your statement has me wondering if I'm missing more than I realize by putting off reading the book. Can you give me an example or some examples of things in the book that didn't sink in until you saw the illustrations and visuals?
