In my opinion, one of the most important skill in the interpersonal communication is self confidence. In fact I think its a really important skill in every aspects of life.
Lets first describe it. Self confidence is based on knowing your value. By beeing aware of your qualities but also your defaults youre able to know your capacities and what you need to be better at. Its close to self esteem. Actually, great self esteem leads to self confidence. Self esteem is about loving yourself for who you are and be ready to learn how to do better instead of juging yourself.
Now lets talk of how it can affect your communication with others. Self confidence is key for a good interpersonnal communication. Thanks to this youre easily going to speak to other. Because you know your value and dont put it in others hands youre not going to be afraid of others jugments and neither of rejection. Also by being confident your way of talking (for example, speaking loudly enough, taking place, making gestures) is going to make people willing to listen to you. This is why people with great self confidence are often natural leaders.
To finish, self confidence and self esteem leads to humility. By knowing that youre not perfect and its ok it helps you being nicer to others and consequently accept them the way they are.
