If you work in sales, congratulations. Sales make people strong negotiators, psychologists, managers, and speakers. Good salespeople can handle almost any business task. The author of this book, the famous business speaker Maxim Batyrev, at one time worked in a large consulting company from a sales manager to a member of the board. Each case in his practice is a lesson for the future, his kind of tattoo on the heart. There are only forty-five of these tattoos here, but in reality there are many more. If your job involves sales, you need this book.
