Learn to use more gestures
As ToastMasters.org states, most people use gestures less rather than more. But those who come across as confident also emphasise what they are saying with appropriate gestures. The first step, then, is to go a little beyond your comfort zone and generally start using more gestures when you speak.
Maintain eye contact
When talking to someone, maintain eye contact. Do make rapid eye movements but stand firm by what you are saying even in terms of eye contact. If you are speaking to a group, try not to keep jumping randomly among listeners; always maintain eye contact with one person for at least a few seconds before "jumping" to the next.
Do not be afraid to draw attention to yourself and put yourself in exposed areas
The very position of your body in relation to others says a lot about you. If you hide in a corner, you will never appear confident. And vice versa. If you walk into the middle of the room and start talking, people will listen to you because they subconsciously feel that someone who has the courage to stand in such an exposed position has a lot to say on the subject. And so it is worth listening to them.
Learn to pause, even non-verbally
Emphasise your main ideas by pausing after you have stated them. This includes non-verbal means. Having made a point in a conversation, give the other person time and space to absorb it. You can do this by stopping talking and gesturing for a moment.
Practise in front of a mirror
This might feel uncomfortable but it is very effective. Get rid of any shame by practising gestures in front of a mirror. You will find you can identify a lot of bad habits, but also discover strengths, which you can then accentuate more.
Smile
Smiling is one of the strongest non-verbal signals that you are on top of things and do not lack confidence. In fact, a person who is afraid or insecure about themselves usually does not smile. And when they do, they smile in a nervous manner.
