Pro Suggests that not all changes be made at once
Where many productivity books encourage you to start everything at once, Zen To Done takes a different approach.
Realizing that making a large number of changes at once can be discouraging, it suggests that you take your time implementing the changes (recommending a year to do so).
Pro Adaptation of "Getting Things Done"
The author of Zen To Done realizes the potential in the book "Getting Things Done", but acknowledges the ways in which it can be discouraging for some people, and a hard lifestyle change to maintain.
Zen To Done applies those same concepts presented in "Getting Things Done", but with a much slower approach.
