The logic in the brain is chaotic, and sometimes a question is not clearly expressed and there are few words. How can I change?

The less you talk, the more you should exercise, otherwise you will never be able to express yourself clearly. You can talk to your best friend and try to express your opinion. No one will laugh at you. If you want to change, you have to be thick-skinned, make more friends, have a wide circle of friends and become cheerful. If you talk too much, you will naturally change.
