The writer, David Niven thought of this awesome book, in which he had outlined the consequences of methodical studies, and arranged them in a manner that can be read by all the individuals and can be executed in their lives too.
The language of this book is really upfront and can be understood by anyone who reads this book. Readers who need to know the source of this book, can find it in the reference at the back of the book. It is an amazing motivational book, I must say a worth buy. I highly recommend this book. Especially to those who love to read motivational stuff!
