Networking presentation

I was an introvert person.After being to many networkings, I started to gain confidence in communicating with people.My intention is always to improve myself.
In each networking, I learnt through my own experiences about good presentation and poor presentation image.And still learning.

-Introducing yourself is a basic manner which everyone knows.

-To speak with tone of neither low nor high.

-In term of giving or sharing information, I would rather keep quiet and listen more if I do not have certain/correct information.

-To use appropriate language

-I find that when people using hands overly, you couldn't focus on what they are talking about, but eyes just happen to keep looking at their hands.

-Personal grooming is important.And also how confident when you are talking, walking and how mindful you are.
