A person cannot do without communication. In this process, he participates a significant part of life. The information obtained as a result of communication is diverse. The personality is arranged in such a way that when receiving new information, he tries to immediately tell another person. This can be fraught with various troubles, so you need to be able to "keep your mouth shut."

Be restrained. The main problem of chatty people is incontinence. They try to intervene in all the events that occur around them. They can't wait to talk to others. Becoming a reserved person is not as easy as it seems. To do this, you need to attend special trainings, because incontinence is a personality trait that has been forming over the years. Sign up for courses on NLP and personality building.

Try to talk less. If you are eager to share news with someone or get into someone else's conversation, then start a dialogue in your head. Talking to yourself is not considered abnormal. This is a kind of psychological relief. A conversation can replace reading, problem solving, labor. Try to distract from thoughts that want to become words. You can hum your favorite tune in your head.
3
Start a hobby. This will help you to be concentrated. The more a person is concentrated, the less he is drawn to talking. Any words interfere with concentration, so focus only on your hobby. Moreover, this is a useful lesson that will help expand your horizons and find new friends. If you do not have time for a hobby, then the same can be done with work and study. Focus on this, and your tongue will remain in the teeth for a long time.
