The book is divided into roughly 3 sections: for the budding entrepreneur, for the micro (i.e. one man) shop, and for the small (under 50 person) business.
Pages 1-25 and then 129-144 focus on what to do/understand before you actually start your business. Based on my own mistakes in the professional service field, I'd like to have seen a statement or two about don't quit your day job until you have a paying customer, but Mr. Fox gets close enough to the ideal. That said, if you are a micro-sized business (10 or under people), this is good refresher stuff and may even give you some ideas to tackle to improve your business. If you are over 10 people in your business, consider skipping these sections.
In between page 26 and page 128, the advice applies equally well to micro and small businesses, although pages 92-97 are only applicable if you have more than 10 people working for you.
Throughout are some real gems of advice ... and more importantly ... the logic behind the advice. The ones that I found most intriguing and resonating were:
1. Cash in the bank is more important than "to be collected" profit
2. Stay off committees, boards and other time-intensive activities that networking gurus often proclaim as key to building business
3. The difference between a penny-saver and a penny-pincher, and why you want one but not the other.
I've read nearly all of Mr. Fox's books, and this is certainly a good one that deserves to be read by anyone thinking about starting up their own business or anyone currently running their own business...or anyone working in a small business.
