I had the same thought as you about his books, if this is the methodology. But I also find it very inspiring, and am extremely envious. Every time I think, "Maybe I should write a book about this", I immediately project myself onto a prospective consumer of my unwritten book and think, "I wouldn't read a book written by me on this subject, because I am not enough of an expert, so why should I expect anyone else to feel differently?", so I don't write the book. This guy thinks the first thought and just goes for it. The word is overused, but: awesome!
