[EX Q]: This is the worst book on personal finance that I have ever read. I would recommend this book to those with no economics background! Nothing new here. Buy Michael Lewis' books instead. The advice given by Mr. Kiyosaki are similar in nature but much superior.
[EX A]: Bad review

[EX Q]: Nice book, the only thing I didn't like about it was that each time a new topic came up throughout the first 30 pages or so we learned more than needed and it wasn't very interesting. It also gets a little boring around page 100 but does pick up. If you think you're going to take pictures of every bird in a local neighborhood, buy several books on your own first, this book is an okay one for that.
[EX A]: Good Review

[EX Q]: I love listening to this. It is soothing music. However, the music will not work on my Kindle Fire. This kind of disappointed me.
[EX A]:
Good Review
