Rilke wrote in Autumn: Whoever is lonely at this time will be lonely forever. I want to borrow this sentence: Anyone who is stupid at this time will always be stupid.

Over the years, our learning, thinking and experience will lead to the development of our IQ. When we were young, we thought 3+2-5 * 0 was a problem. Now we think it is simple because of our IQ development, so we think it will continue to develop. We have heard more than once that people have unlimited potential, and we are unwilling to admit that people's IQ has limits, However, from another perspective, it is easy to accept that no matter how hard you try, your speed in the 100 meter race is still lower than Bolt's, and you nod your head to think that it is true. If you have a struggling excuse, you may say that the physiology and bones of black people are different from our Asian race, but it is also agreed with indignation. You can run and see if you are not the first to win. But why is it so difficult to admit the limit of IQ? Maybe no one in our subconscious wants to admit that we are a fool. I don't know who said such a sentence: Sometimes you think your unreachable high point is just the starting point of others.

I admit that I am a fool.

But the world is by no means built by genius. I would like to console myself with this.
