I was pleasantly surprised this was based on principles and not actually habits such as exercising first thing in the morning and meditating. It is based on foundational things and laid out well. In the additional resources at the back, he mentions he normally teaches habits 4, 5 and 6 and then 1, 2, 3 - which makes me think - why not switch them around? It also wanders into the realm of forgiveness which I think is unnecessary in this context. Overall, there are things I am using in my life and will continue to do that I believe will enhance it. Although, I skipped over the areas and examples I felt weren't relevant
I've come across few non fiction books that are hard to put down, but this is one. I have read many self help books, but few as insightful and helpful as this. The many examples help illustrate how a person might apply the principles in their own life.
