I gave this book five stars. It's full of excellent content, but for six stars it needs to be more entertaining and have a better ending.The audience for this book is anyone who wants to improve their career or be part of a winning team, and / or especially leader CEO types. If you’re just looking for career improvement essentials skip to the last few chapters. However, the insight into how your leaders think will prove useful, too.According to Jack: Business is a game that should be regulated by government and conducted fairly and honestly and therefore it is a game that must be won. He says winning is fun and if you’re not having fun, you’re doing it wrong!Mr. Jack Welch is an American business executive, author, and chemical engineer.
