How difficult it is sometimes to decide to take an important step: to speak at a meeting with a new proposal, to defend your idea, to ask for a raise, to change jobs. The main reason is self-doubt. And for women, this problem is especially acute. After all, it has been scientifically proven that women rate their abilities much lower than men. It is common for them to attribute their success to a happy coincidence, and any defeat is perceived as the collapse of their whole life. The authors of this book conducted a global study, talked to the most powerful women in the world and found out that even they constantly doubt themselves. So what is self-confidence? Where does this quality come from and how to develop it in yourself? This book will help you overcome inner barriers and decide to finally change your life for the better.
