Knowledge can indeed enhance people's self-confidence and sense of security because through learning and understanding various things, people can better understand the world and themselves, and thus better deal with various challenges and difficulties. However, knowledge alone could not solve all problems. When we learn more, we may find ourselves facing more problems and challenges because we need to use what we have learned to solve problems and constantly learn and update our knowledge. In addition, we also need to consider some personal factors such as emotions, interpersonal relationships, and personal values. These factors may affect our knowledge and our view of the world, causing us to feel uneasy and insecure. So we need to realize that knowledge is an important tool, but we need to combine it with personal growth and self-actualization to better cope with the challenges and difficulties in life. At the same time, we also need to adjust our knowledge and view of the world to better adapt to our surroundings.
