As usual in this kind of book there is a lot of padding. Indeed the author writes two pages when few sentences could be enough and you will also find basic generalities such as "Be nice with your client" or "don't forget to sleep". Finally the author will never miss a chance to remind you how great this book is and how stupid it is to do a real MBA.. sensitive debate I agree but when the author does it every 10 pages it becomes unbearable.
YET, this book develops some interesting and useful ideas, and it is very easy to read. Even though you're not interested in creating your own company, you may still find this book interesting by the working methods and the psycological analyzes of human behaviour you can find and how these analyzes can be adapted to companies.
In the end I would recommend this book, even if you're not interested in entrepreneurship, but it personally did not change my life.
PS: I advise you to skip the first chapter of the book, where the author tells you how great his book is, how clever you were to buy it and how MBA schools are lame (40 pages...). And sorry for the potential mistakes in my critic, english is not my native language :)
