I have earlier read the book " The unusual billionaire " of the same author and found the said book very interesting and useful for building my long term portfolio. Keeping in view of the same , i purchased this book from Amazon. However, i am totally disappointed by reading this book. The authors have not added any practical guidance for building long term portfolio. i think this is total waste of money for purchasing this book. I was not expecting such book from the renowned author Mr Saurabh and his colleages.
