People seem to be intrigued by what successful people did and how they did it, and we often see it in the media. However, once they achieve great success, they become distant from ordinary people and seem like people high in the clouds, so biographies of great people often don't resonate with them. But it seems that even successful people often have experienced feelings of despair and misfortune. There is no way that the following episodes will directly lead to success. Rather, why were these people able to achieve such great things that they have left their mark on the world? It may be because they overcame adversity.We hope that this will provide some hints and encouragement to those who are currently going through difficult times.
