Query: Where was this book when I was 20 ?!

Getting closer to 40, I've begun to think more about money, since my parents told me to get good grades and a good education, find a good job and everything would work out fine. In reality, our social security system is beyond bankrupt and it's clear that I'm going to need more money for retirement; this book is full of practical information to change your thinking and your attitude about money.It's a must read for everyone but more importantly it is a must-make your children read book for parents.If I had this book in high-school I would have more assets, less liabilities and would have known to pay myself first. Because of this book I have begun to look seriously at my life and for the first time I can see the end of the cycle. I love this book.Other Great book that have made a big impact on my life are Good to Great by Jim Collins, Think like a Billionaire by Scott Anderson and Think and Grow Rich by Napoleon Hill
