Our entire life, we have to deal with people all around. It will be easier for us to live happily if we get along with them. People need people to survive. Look at it this way, suppose you are sitting alone and there is no one to talk to. This same situation goes on every day for days and years. Will you be able to survive this? No, right? So it is important to connect with people and get along with them to avoid disputes and arguments.
Try to state something positive when you agree with an individual and during an event where you disagree with the other person, try to say something that would not cause any contention. Always reply in a polite tone so that matters do not get heated up. Try to listen actively to what the other person is saying. This makes him feel important. Understand what they have to say and give feedback accordingly. Prevent yourself from making statements that can offend others. Insulting, reviling and abuses will just exacerbate the situation. It is smarter to disregard others' negative conduct than to act like them. Be empathetic and try to put yourself in their shoes. Get along with others and make them comfortable around you.
