Often, insecurities can manifest themselves in subtle ways that we don’t even notice. One of the most revealing details that can show weakness or insecurity to others is body language. Therefore, if we want to convey confidence, we must pay attention to how we move and communicate through our gestures
Slouching
A slouched posture can indicate a lack of confidence and security. When you slouch, it looks like you’re trying to take up less space, which can be interpreted as a sign of weakness.
Avoid eye contact
Not looking people in the eye during a conversation can give the impression that you are nervous or disinterested. This can make others doubt your confidence.
Nervous gestures
Playing with hair, biting nails or rubbing hands are examples of nervous gestures that can reveal insecurity.
Speak softly or stutter
Speaking in a low tone or stammering when expressing yourself can make you appear less confident and less convincing. You can rehearse your words in front of a mirror or record yourself to hear how you sound.
