The book is surprisingly light on the method, but very heavy on the "yes, man, wow" of keeping doing the method (and, would you have thought it, buying the special notebooks, though they're most certainly not required).

So, I've got some way through the book, and realise that it's essentially the same as my rather more rudimentary attempt of keeping a task list in a paper notebook and copying it over every morning, which has the effect of self-pruning the task list, since it's relatively clear if I've copied something over five days in a row, it's really not going to be done.

I don't see much benefit in the "logging my thoughts" aspect of it, though I could see that as a busy manager it might have been useful. So it's not a bad book, but just not really very brilliant.
