I bought this book hoping it will support my studies at university, i couldnt be more wrong. Book has no mentions of actual companies(maybe apart of johnson&johnson), ideas are vaguely expleined and language used is far from professional. possibly authors idea was to make it more appealing and informal but it seem more of unprofessional to me. one of ideas is called S**i happens.. well thats how would i descirbe this book! S**t happened and i wasted my money. i wouldnt even recommend this book to use it as loo time read!
