In my opinion, many people are already overestimating their abilities. Once upon a time, everyone said that they are not so smart and don't know a lot, although in fact they were smarter than others, but now it's the other way around, and it's scary because when a person says that she knows a lot, you can rely on her, but when her knowledge is needed, it turns out that she lied. How would you describe yourself, you are smart?
