I bought this book because my teacher recommended me to read this book. Because I was having all negativity in my life because of some failures that I came across in my life.I thought before reading the book that I am good at nothing.I was very pessimistic.
But I started reading it, it really filled some energy and motivation in me.That today I am having a very good job in a big MNC plus I am also becoming a optimistic now.
So, If You need all motivation in your life that you can do.Go for it.
