Though I have never attended a business course (not to mention an MBA) I was very interested in the book. I read many articles and discussions on MBA courses and some of my close friends attended them too. I find the book quite good. Lot of useful information on business. A few chapters are kind like reading a self help-book but I find them useful as being successful in business depends a lot on the personality of the entrepreneur/owner. Highly recommended but do not expect that it will substitute a business course. Mainly because reading the book will help you to learn some techniques in business but you will not get the contacts like in a school.
