"Good advice for simplifying/organizing"
Sure. It serves more as a reference guide than a "read through once". The advice on organizing your file system was very good. I feel like I've finally got a handle on my personal files.
Good, simple, sound, logical advice.
No.
Clearly the author has had some emotional and panicky clients, because he spent a large portion of the book telling the reader to take a deep breath, don't panic, etc. Just a little too much cheerleading for my tastes, but if you ignore that, the information contained within is good.
