I’d already heard of the 90 minute rule Before I read Nigel Botterill’s excellent little book, and tried incorporating the principle into my life, with varying degrees of success. It is an idea that’s already quite well known now, and there are several useful and informative websites on the subject you can access. So why buy this book? Well, it goes a little further than the sites. It’s a primer, but also a step by step process to incorporating the concept into your daily work-life. It’s a short, sweet read – designed to be read in 90 minutes. It seems insubstantial at first, over-padded, a concept stretched to transparency; its simplicity is deceptive. What you get here is actually series of easy-to absorb lessons disguised as short, snappy chapters. The first half of the book is a series of anecdotes: real-life examples of how people used 90 minutes a day to build successful businesses. The second half is more intense, using short exercises and thinking-breaks to get your mind working on how all this can work for you – a series of thoughts, ideas, ‘what ifs’, that are gently – almost sneakily – imparting knowledge and sparking ideas. The second half is better than the first. In my everso humble, you can skip most, if not all, of the first, anecdotal, ‘Mrs P. of Swindon did this and now she’s a millonare!’ chapters. It won’t be as enjoyable to read, and possibly not quite as effective as a learning tool, but there are an awful lot of case histories in the first half and the second half is where the meat and potatoes is – all the ideas on actually using this process in your daily routine. I’ve been using it myself to enormous effect. It has had a remarkable benefit on my own work-practices and productivity. I am getting so much more done and am less stressed and tired while doing it. I really do recommend the 90 minutes concept and this book is a great tool for getting you started, then up and running. I really am very pleased I read this book; I can’t recommend it too highly.
