6. Lean forward
You might want to consider your posture while having a conversation with another person. Especially when you are seated, leaning slightly forward can make a vital difference. If you lean slightly forward, it shows to the other person that you are really interested in what they are saying. Also, such a posture sends a message of self-confidence by decreasing or removing barriers between you and your conversational partner.
On the contrary, if you lean backwards, it shows to the other person that you might be lacking in interest. And that never sends a positive message.
