This is an updated version of his previous book "What not to spend", so if you own that book then turn away now. If you haven't and this is the first money book that you have looked into then read on.
The simplicity of this book is what makes it readable. Most chapters are a few pages so you can dip into and out of it at your own pace. Some of them are padded out with quite random photo's of Alvin, but you do put that to one side. The order of the chapters is quite logical, starting with identifying where you are; moving to planning what you want to do and then finishing with the steps that you can take to get there. The advice is not revolutionary, it is simple and direct. The basic motto seems to be see yourself like a business and then ensure you are profitable and have a good cash flow.
What is quite good about the book is the way it takes complex areas of investment and seeks to explain them in a straightforward way. It gives you some motivation to improve your long term prospects by shifting to saving and dipping your toe into investments. It doesn't lay out everything you need to know, it sets out your options then gives you a gentle prod. The rest is up to you.
