Make yourself confident and pay attention to your tone when you speak.
In fact, introverts are often particularly inferior. They are afraid of communicating with others and being rejected, so they don't know how to contact with others at all. In fact, if you want to make friends, you must become confident, talk to others as much as possible, get in touch with others more, be considerate of others in the process of contact, and speak in an easy-going tone, because only in this way will others be willing to get along with you and feel that it is good to be friends with you.
Chat with excellent people and try to talk about topics of interest to others.
Because I am introverted, I don't know how to speak and how to communicate with others. At this time, you should encourage yourself to come out, communicate with others more, get in touch with excellent people, learn from their strengths and make yourself excellent. Only when you become excellent will you feel confident when talking to others. Of course, when you talk to others, you must talk more about topics that others like, because then others will think that you have something in common. I will feel the same way with you. You two won't feel embarrassed when chatting, or even bored when chatting with you. After all, there are not many people who speak the same language, and others will cherish you.
If you can do this, I think you will find friends, so you must learn to change your introversion. Only when you change yourself will others like to get along with you.
