Brilliant book, definitely worth reading for all age groups. Personally, everything written in this book motivated me in the right direction and helped me identify areas in my life where I was not striving hard enough. Many books have a suggestive tone but this book not only suggests you killer habits but also many easy ways through which you can habituate yourself to these. This can be a great gift for your teenager or pre-teen child of an impressionable age if you are a parent.
The real life accounts given by the author and the team are wonderfully fresh, moving and inspiring to the core. It talks about many real life heroes who have slayed the difficulties of reality and emerged successfully.
For anyone who wishes to reset their drowsy and sedentary lifestyle, THIS IS THE BOOK.
