If you want to know why, then you should find the reason from yourself. Fundamentally speaking, it is not that you are stupid, but that you are too smart. Why do you say that? Try to think about it. Do you think I can do a good job without working too hard? If you really have this idea, it means that you are too self-centered. In this way, you can't see the difficulties except yourself, and feel that your own business is the biggest.

How to get rid of it? Remember one sentence: smart people work hard. Ask your parents more. Ask people around you more. Don't be complacent, and don't wonder why your efforts for a long time still have no effect. Remember, stick to it.
