The human brain evolved to be fast rather than completely accurate in order to make quick decisions to avoid predators. While this leads to generalizing and not having a full understanding, it generally works well. It is important to find a balance between thinking enough to act but not overthinking to the point of being stuck, as those who can consistently act with just enough information tend to do better and gain valuable insights from their experiences and mistakes. The rare ability to make decisions and learn from actions can be more valuable than any specific skill set.
