What truly sets people apart in life is not information, education, or effort itself, but the ability to think independently and deeply about problems. Many people only focus on "what to do" when faced with a problem, a few will ask "why is it like this", and even fewer will continue to dig deeper until they see the underlying structures, rules, and mechanisms. On the surface, the difference is only the depth of thinking, but in essence, it is a difference in information processing: information is already abundant, what is truly scarce is the ability to deconstruct and reorganize information. Deep thinking is not about thinking more, but about refusing to accept conclusions directly, continuously asking why, and ultimately penetrating surface-level issues to reach a systemic understanding. Ordinary people solve problems; experts understand how problems are created. The former patch results, the latter change the rules. Therefore, the core of the gap is not about how many things you have done, but whether you are repeating similar problems or constantly approaching the essence of the problem.
