Hi everyone, I'm 20 this year and I've been thinking lately about the question of how people can become more mature and stable. I think real maturity and stability is not pretending to others but being able to calmly analyze problems when encountering them, as well as being able to take care of as many people's feelings as possible when solving problems. But at the same time, I also have some questions about how to become mature and stable, and how to show a convincing image in daily behavior, such as in words, gestures, and facial expressions, do you have any suggestions in this regard?
