I've read a number of books on how to start a business.
The only criticism of this book that I will accept is that it is sketchy on details, and you may have to supplement it with a more specialised book on starting a small business.
However I think this was also a strength of the book. Instead of drowning you in details, they get to the point really quickly, and describe the key things that you need to do. I also kept finding myself thinking that the points they were making were right on the money.
I reject the critcism that they come from such a priviledged background, that success was assured. I think that this is missing the whole point of the book. Whatever your starting circumstances are, you can follow these steps and establish a business. It may happen quicker if you have a lot of money already, and you may not have to juggle a day job at the same time.
However if you really want to do it, you can, whatever you started with. There are plenty of examples of people who've done this from all sorts of backgrounds.
So the real issue with this book is whether the information in it is likely to help you start up your own business.
I think this book definitely achieves that.
The approach they give you is spot on. Even better than that, is how they demystify some of the steps, and encourage anybody to have a go at it. Most of it isn't rocket science. Some of the steps may require some technical assistance, but they make it clear that a lot of that assistance can be obtained for free, if you are proactive enough to go and look at what's available.
I found this book useful and inspiring, and not just as a good read. It's a genuine guide to what you need to do to start a business.
