The business world dictates certain unspoken rules to women. You should not unnecessarily demonstrate your mind and strong-willed qualities. Do not show your ambitions and desire to move up the career ladder. In addition, women are held back by their own, internal barriers. There are hundreds of really good reasons why women give up on their careers. They do not allow themselves to move forward because of a lack of self-confidence, an unwillingness to draw too much attention to themselves, because of the constant dilemma, what is more important - career or family, because of a pathological lack of time. As a result, today only 4% of the leaders of the world's leading companies are women. Sheryl Sandberg, COO of Facebook, one of the most influential figures in the business world, shares the obstacles she has faced in her career. This book is a manifesto and a source of inspiration for those who believe that a woman can and has the right to seek self-realization in a career and business, and family relationships should be built on the basis of equal partnership.
