Query: Borrow this, don't buy it...

I would rate this book as "OK". It shared some valuable information, however it was entirely too short to cover the numerous topics in any real detail. I would recommend it for someone who is trying to figure out what information they should seek out. It was a quick & easy read, so not a complete waste of time. I do agree with the above poster that it can be condescending and annoyingly repetitive. Borrow it, this holds absolutely no long-term or reference value.
