Query: Isn't it all just common sense?

I am amazed and how "helpful" people find this book. The only thing worse than this text is the 3 day course that accompanies it if you are subjected to such evils by your employer. My advise is take the time that it takes to read this book and "sharpen your saw" the old-fashioned way... live a little! I'm sorry that I had to give this book one star... zero stars was not an option.
