One of my friends told me to read this book. when I personally read this is changed my way of thinking as this book has changed many lives across the globe. Actually this book is a fine piece of work and a great addition to literature and door to success. It’s like book speaks itself because of written expression is so easy that a non native can read easily.
I personally recommend this book to everyone especially teenagers. I suggest book The 8th Habit from Effectiveness to Greatness similar piece of work by Stephen R Covey.
