Learn the psychology of the other person

Learn more about someone’s personality.
When interacting with people, pay attention to their social circle, actions, and even how they talk. That's how you can tell if someone is introverted or extroverted.

Find out what motivates people.
Focusing on what motivates others could probably reveal who they truly are. So, think about what is someone’s drive in life. Is it their career or establishing a family? You'll notice many of their personality traits after that.

Practice active listening.
Many of us are more inclined to talk about ourselves than listen to others. But, if you want to read about someone’s character, you must converse with them to find out more about them.

Pay attention to others' body language.
When you interact with someone, observe their posture, look, and even smile. The next time a person is sitting with their legs and arms crossed in front of you, try to break that barrier between you.
