A week ago, I had the great pleasure of reading an e-book, When Money Talks, Listen! by Rich Ezzo. It took only about an hour to read.

When I first received a copy, I thought it was a Get Rich Quick type of publication. Nothing is wrong with Get Rich Quick, but my mind just doesn’t run after dreams of wealth. I think that if God ever wants me to be rich, he knows where to find my purse.

When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn’t money hungry either. He, too, is hungry for more important than money.

Since I love this e-book so much, why wait a week to write the review? Simple. I wanted to see if the effect it had on me was a keeper. After reading the last word of the e-book, I totally agreed with the subtitle (副标题) which promised to forever change the way we thought about money. I had so many thoughts running around my mind that I had to install (安装) a stoplight to stop some while others made their way into the picture, then I yielded (让路) them as a few ones arrived in town. I had a mental traffic jam, which only goes to show how slow the traffic usually is.

It has been a week and the effect is the same. I truly do look at money differently and have even done a few things differently this week. This is an e-book you ‘ll want to read, I promise. I often recommend books to my daughter, and this is one that I didn’t just ”suggest”----I left it open at the bottom of the compute and told each one ,”Read it, you’ll love it “.

I would never point someone in a direction I wouldn’t go myself. I strongly advise you to visit the author’s website, Myster Money, and to download the e-book. You won’t regret it.
