Why do I think everything others say is nonsense?

This means that you have begun to have your own thoughts and opinions on everything, and you are no longer just following the crowd. In a sense, this is Good thing.

There is nothing wrong with you thinking that others are talking nonsense, because maybe that person is really talking nonsense, but in fact you don’t understand anything. If you have such an idea, it is best to add a premise, That means you really understand what he is saying. For example, I told you that the rocket is actually a big Sky Monkey. A rocket that big is actually filled with gunpowder. Then when the countdown ends and someone shouts "ignition", someone will light the fuse and ignite the Sky Monkey. Monkey, oh no, it’s the black powder in the rocket, which then generates huge thrust and sends the rocket into the sky.

My example should be easy to understand, but not all the things people say are so easy to understand. You may not know some things that I think are common sense, so what do I say, you I don’t know if it’s right or wrong, so of course I can’t tell if I’m talking nonsense.

If you feel that other people are talking nonsense whenever they express their opinions, no matter whether it is knowledge you understand or not, then I think you have to find out the reason from yourself. I am afraid you have more than just It’s so easy to have your own opinion, and you may have become a little overconfident and developed into arrogance. Do you remember a text you learned in elementary school? It is about a bird at the mouth of a well saying to a toad squatting below, "Come up and have a look, the sky is really big." But the toad said, "Little bird, you are talking nonsense. I have been looking at the sky, but it is actually a round sky." Just small pieces. But the bird didn't give up. It made a bet with the toad that the sky was huge and that the toad was sitting in the well looking at the sky. The toad couldn't help but jumped out from the bottom of the well. Then, before he could even raise his head to look at the sky, the toad was bitten to death by the bird. And then ate it.

I have been talking nonsense seriously for so long that I have almost convinced myself. I wonder if you believe it?
