Reading this book is like a "feel good" session with a therapist. It encourages you to let go of your imperfections and live more whole heartedly. When listening to the stories in the book, you realize all those little negative thoughts that stop you from being authentic (for example, "he's being a jerk" instead of "he said something that was true and painful). The journey towards wholehearted living is a practice you would do everyday (or try as much as you can). I'm sure the key points that I take away from this book now are those things meaningful to me at this point in my life. I plan to read the book again and see if I find other things to work on.
The ideas in the book are simple. But that's because the method to change is simple -- find the right approach for you and identify what would motivate you to continue day after day. People often fail because of two reasons. They talk about or read about change but don't take any action. Or they start without having a plan or consider how to get back on track when slipping up occasionally.
If you're ready to make a change, this is a great book to walk you through it. The author describes the steps (e.g., plan and prepare). She gives examples of where people have succeeded and failed in these steps. You decide what would work for you. Go through the book slowly. Absorb a few ideas and practice the techniques. Be willing to tweak it so it works for you (e.g., putting sticky notes to remind yourself rather than beat yourself up when you forget to do something). After accomplishing those steps, move on to the next section in the book.
If you purchased this book because it sounded interesting, you probably don't need it for yourself. There are people with a "fixed" mindset - intelligence and skills are fixed; mental capacity and capabilities are limited to what you're born with. And there are people with a "growth" mindset - intelligence and skills can increase through learning and practice. So if you're interested in this book, you would be in the camp that thinks you can always do better. You don't have limiting thoughts like "I'm not a math person" or "I couldn't... if my life depended on it."
The book provides examples and techniques in moving away from that "fixed" mindset. It covers a variety of areas: athletes, business people, people in relationships, and parents/teachers. The section on parenting/-teaching was the most useful, probably because adults could have a big impact on nurturing or limiting children's potential. Whereas in the other areas, adults make problems complicated and it's hard to get them out of a "fixed" mindset.
