MJ Demarco is a business writer who sets himself apart. Firstly his concepts are tried and tested, secondly he shares as many of his 'failures' as he does his successes and thirdly he translates complex business and finance principles into simple, doable processes.
The book characterises 3 types of people: Sidewalkers, Slowlaners and Fastlaners. Each is well defined and accompanied by the 'illusions' we create to not perform. It's are all there in black and white, so it can be a bit squirmy when you've got to put your hand up and say 'yep, that's me ... I really do that and think that'.
I'd recommend this book to all entrepreneurs whatever stage of business you're at. It's full of truths, practical wisdom, pitfalls to avoid and fast-tracks which you might be just a step away from.
(Oh, and I ordered the paperback from Amazon.com because only the Kindle version was available in the UK - I knew I'd be underlining, scribbling and taking copious notes ... which I did). :)
