I enjoyed this book. It was simple, clear and insightful. It took me a couple hours to read.
The book is grounded in the Getting Things Done (GTD) productivity methodology. It clearly illustrates the basic principles and also shares some other practical productivity tips.
The author strongly supports the use of technology to improve productivity. While the book frequently refers to how things can be done with Nozbe, Evernote etc, the general technological principles would still apply to other apps.
The examples are varied, clear and illustrative. I especially enjoyed the examples about how the author's wife uses this productivity system to her advantage.
As someone who uses Nozbe and embraces productivity techniques, I found the most value in the author's reflection on his business and how Nozbe is being used to manage teams and delegate tasks.
I'd recommend the book to all Nozbe users as they may learn better ways to use the software. I also recommend it to anyone starting to learn the basics about how to be more productive, and wanting to use technology to this end.
