It was a pretty crummy book, I'm pretty glad I got to save by buying it online, at least it got me through that slog of a class

This has saved me so much time in trying to analyze drives that may be going bad.

It is not as useful for me as I would like, but I should also say that I'm not studying it very diligently.

You can tell the author put a lot of work into this book. After reading through most of this book, I've realized that I'm already doing some of these money-saving things, and they do work!

I am a person who make decissions based on emotion most of the time. And I was aware of that and knew that was a reason why I made a lot of bad decisions.

So I decided to buy a book on Decision Making and browsed Amazon then bought this book based on the reviews.

Boy am I glad I did.

I am only halfway through reading it and I am already looking at life differently. I found out I was living in a limited and boxed life!

The book is currently helping me in making decisions on moving to another city and changing my job. and it is doing a damn good job really.

It not only helps you in making decisions, it showes you how life can be more limit free. Mentally and Physically.

Best investment I did so far.

While attending university, I became aware that I was not going to be able to fly through my American Heritage class without the textbook. I promptly went to the bookstore just to get a gauge of how much it might cost me if I were to go the ridiculously overpriced route, should I feel so inclined. As the book cost over $100 and was going to be used for less than one semester, I figured I'd go elsewhere. I checked online and saw this one for $15 bucks! I immediately bought it, congratulating myself for my prowess in frugality.
As my first quiz was approaching (the next day), I thought I would take a peek inside and skim the required chapters so I could BS my way through, as I had done many times before. However, as I checked my notes in class against the material in the book, I quickly realized that the book contained nothing even remotely pertinent to the material.
It was at THIS point, not while I was contemplating purchasing the book, that I decided to check the AUTHOR of the book required by my class.
Needless to say, it was the wrong freaking book. Since it was a digital copy, I couldn't take it back and retrieve my $15 - which meant I didn't get to eat that month (or the next), which is where the 3-star rating comes from. It broke a fundamental rule of collage life: Never trade 2 months worth of food for recreational reading. What? Never heard of that rule? Well, you don't have to take my word for it.
Buy this book and find out for yourself. ;)

I have got a lot of information not only what I was looking for. I learnt things that I didn't know.

If only I had purchased this book a couple of years ago... I would have (probably) saved my marriage from a lot of pain...
