Good posture will give the impression of self confidence (even if you don't feel
that way on the inside). While
walking, it is always important to
maintain a relaxed yet definitive upright posture- spine long, shoulders back.
Relax the muscles in your face to the point
where you have a natural, pleasant expression permanently engraved there. For
some people, it helps to dwell on something or someone that makes them
happy
Orient topics toward the audience.
Control your tone of voice.
Empathy is at the core of charm. If you can't tell what makes people happy or unhappy, you have no way to assess whether you are saying the right or wrong thing.
Never laugh at your own jokes
Never over-explain anything
