One of the main things communicated through this book is to LIVE IN THE MOMENT, and to make your CONTRIBUTION to the world, don't live as an individual but live as a part of something greater. It reminds you that fear is just your friend, and that failure is another stepping stone to success. I can see a lot of connections with Napoleon Hill's Think and Grow Rich. The main aim of this book is to change your MINDSET. Your MINDSET is what makes you YOU. When a friend of mine had read this book and similar other books I noticed a huge change in his outlook to the world, and after reading this book I understand why and how he has changed. I naturally emulated his behavior, but I never knew that a lot of things I've observed have been described here in this book.
I've seen people making fun of inspirational books, but it's their mindset which does not allow them to understand or to value something like this. That can come with time. You have to find the right time to make a change.
