Among everyone I have interacted with, regardless of their academic performance, there is a very obvious feeling:

People who have attended high school generally have a much deeper understanding of problems, better logical reasoning in handling matters, and a greater ability to learn new things compared to those with only a junior high school education.
This is not entirely because high school knowledge itself is particularly profound,
but because those three years of high school happen to be a critical period for the rapid formation of a person's mindset and worldview.
