Always Maintain An Eye Contact

You can predictably determine someone’s emotions from their gaze. Eye contact is the crucial first step for resonance, or a person’s ability to read someone else’s emotions.

Make and maintain eye contact when you’re giving someone feedback.

When you are doing the speaking, you should look the person you're talking to directly in the eyes, but not so much when you're the person listening.

Making eye contact while your interlocutor is speaking actually harms your perceived competence.

Proper eye contact can express that you're invested, listening and accepting of the other, while looking down or constantly shifting your gaze shows lack of interest and focus. Too much or too little eye contact can be off-putting, experiment to find the right amount.
