There’s a difference between being quiet and being a good listener.
It’s easy to think they are the same. Especially if you talk a lot.
“Oh he’s always quiet when I talk” and you think he’s listening.
To be a good listener you need to train yourself to empathize with people because unless you do so; your interest is limited no matter who you are. We naturally listen to what interests us, not just that, but at particular period in time.
Empathic listening is so powerful because it gives you accurate data to work with. Instead of projecting your own autobiography and assuming thoughts, feelings, motives and interpretation, you're dealing with the reality inside another person's head and heart. You're listening to understand. You're focused on receiving the deep communication of another human soul. - Steve Covey (7 Habits of Highly Effective People).
Listening is more about being present. Focusing your mind with who you are having a conversation and what they’re saying rather than allowing it wander.
Else you only pick what sounds interesting, and worse completely giving your own suggestion or advice without paying attention. It encompasses use of more than the main sense organs; but also the heart.
Listening is a skill. It takes practice to read faster and assimilate than normal; so is listening attentively. We spend years learning to communicate, read and write, how to speak but how about listening? Listening is a skill. For you to be better, you have to practice.
It may be a little uncomfortable, but learning to listening would largely influence your level of influence with others as it inspires openness and trust.
