What is an "assistant" to the manager? Oh, this is an extremely versatile person! At times - a real gray eminence, very often - the first after God, and always - a super agent, "perfectly" coping with impossible missions. And the invisible man, and a wise psychologist, an expert on human souls, and, if necessary, a subtle manipulator - behind the boring definition of "personal assistant" lies an infinitely wide field of activity. It is impossible to know in advance what kind of feat a new day and your own leader will require from an assistant, and it is impossible to become the Right Hand of the Boss by reading textbooks. With one exception: the book you are holding in your hands will really help! The basics of the profession and its secrets, tools, tricks, tips and life hacks - they are shared with readers by the most experienced agent "two zeros": Personal assistant with number 900.
