There's is this general mistake everybody keeps and more importantly, we do it without knowing.
But the enlightened ones amongst us know this intuitively or intentionally; so they do what is right.
The credo is simple; *Speak To People about their interests and their concerns*
Most at times when we are relating with people, we try to talk about ourselves, our interests forgetting that the most interesting thing for others are their interests and their concerns.
Unless they show concern for your interests and your concerns , it's best to focus majorly on their interest and their concerns.
Because they like to hear about themselves; they like to hear about this they love.
If you know this simple rule; your conversation might not necessarily improve although it might but people are more likely to perceived you as interesting to talk to and being around.
But don't get me wrong, the goal is not necessarily to talk about them throughout the conversation but just to be aware that people mostly like to be spoken to about their interests and concerns.
