How to assess a person's level, you can look at these three points: First, what they dare to do. If it were you, would you dare? If you wouldn't, then it shows that they have more courage, more ability, and are stronger than you. Second, the issues they think about. Do you have the same depth and breadth of thinking? If not, then their depth of problem-solving is worth learning from. Third, never doubt someone who has more wealth than you. Their IQ is not lower than yours. No matter how absurd their ideas are at the time, a person who is at a higher dimension than you surpasses you in all aspects. Things that may seem impossible for you might be just a piece of cake in their eyes.
