I found this book to be quite informative, especially for those who are beginning to handle their own finances. I have been tracking my finances for some time and recently watching those expenses so that I can reach financial independence sooner. Still, those book was helpful in rethinking some things and reinforcing others. Yes, it is not the perfect book on financial independence but it is a very good book in assisting one in rethinking how they handle money.
I am a frugal person by nature, but have changed my perspective and approaches to reach my goals sooner. Not everything may work for everyone. Each has to find their own path and figure what works for them, but this book is a good start and should be a recommended read.
