Zen to Done

This was not great.

While I appreciate the core idea of “GTD but one at a time” the book never really goes beyond this and ends up repeating a bunch of sentences over and over again. And I'm not even sure if the strategy of only doing one habit of GTD at a time makes sense.

For example if I decided to to the collection habit for a month and was very diligent at collecting all my open loops, productivitywise I think I would still be in a terrible position because the collection habit only makes sense if you are reviewing the lists you make also. If you are not regularly reviewing the list you collect open loops on your brain is probably going to pick up the loops because it doesn't trust that you will deal with them at some point. Or at least this is what David Allen would probably say, and I would definitely believe it.

The problem, though, is that it's not just these two habits that depend on each other but almost every habit in GTD and ZTD depends on each other. You can't have collection without review just as much as you can't have review without organisation.

The idea of doing only one of these habits at a time is not something I could imagine happening in any succesful way.

On top of that, even if I had to assume that you could somehow make this work by only doing one habit at a time, I found the actual content in the book very light and not nearly well substantiated enough.
