It takes about 3 seconds to read 2 pages. There are about 100 pages. Turning the page another 2 seconds. Add another 10 minutes for an occasional reflection. Most people will read this book in about 15 - 20 minutes. Took me months. I would give each thought a couple of days of reflection.
An okay coffee table book. I'm happy to say that my answers to most of these questions were in the affirmative or otherwise positive. But that's not to say I walked away inspired.
