There was a review here that was unjust. The guy complained about the books simplicity and that it should be reading for kindergarden.
Well I run my own business which is successful (meaning: debt free, great cash flow, wonderful income, will retire in my 40s to pursue all those other life goals). Presently I am buried up to my eyeballs in daily issues like sales projections, new products, marketing, accounting, etc. The trees were obscuring the forest when I picked up this book. It's simple list of things to do was refreshing and I was shocked that out of my University degree and over 30 business books on my shelf, there were a number of simple things I had overlooked.
Other books bury you in chapters, what this book says in sentences. The other reviewer looks like one of those many MBAs who dream of being a CEO of S&P 500 company and believe in making the simple things in business complicated for their own ego.
If you really run a small business then I would pick this one up to re-focus yourself on the simple things to success. It is easy to forget the simple steps when you are busy and you start to wonder away from what makes you successful. This kindergardener is happy to find a point or two that has paid for the book 100-fold.
