the book is very good and can motivate you a lot. though it is inspired from real life war events of the authors yet what I see is in every chapter in 'Application to Business' section the higher official doesn't know how to deal with their problem. wilik and babin come at their rescue, give them a solution and the officials react how simple it was we didn't know that. this made it a bit dramatized scenario. Nonetheless, indeed a must read.
