This will help to understand some of the features of relationships between people. And, of course, you need to communicate with people. The more a person communicates, the more skills he acquires. Communicating with different people, a person gains invaluable experience. We all learn from each other and learn from our mistakes. In general, there is no need to rush the time. In general, in a normal average person without mental disorders, the calendar age fully corresponds to the psychological age. Do not chase ahead of time.
