1, find an idiot to perform. If you feel stupid, you must have handled something wrong, or didn't speak well, or didn't do well in the exam. In either case, you should seriously reflect on the reasons and performance of your feelings, because only when you know that you are stupid will you know how to avoid it.

2. Give yourself confidence. No one is perfect, and there is no shortage of gold. If you always feel stupid, you will lose confidence. Give yourself confidence properly, and you will have the courage to work hard and do better.

3. Try to solve the problem. No matter how stupid you think you are, the first thing to do is to solve the problem. When you try to solve a problem, you have experience, and it is possible to do things right. Maybe you will find that you are not that stupid.

4. Learn more. Cleverness is embodied in learning and knowledge. If you don't study and work hard, you will never be smart. Only those who work hard will have enough foundation to deal with problems and challenges, and they will also get up in their daily growth.

5. Ask smart people more. Experience comes from your own practice, but if you can consult those smart people more and learn their methods and thinking methods, you will take fewer detours than others, and you will become smart.
