1. Avoiding Eye Contact: Individuals lacking confidence often avoid making direct eye contact with others. They may look down or to the side rather than meeting someone's gaze.

2. Slumped Shoulders: Poor posture, such as slouched shoulders or hunched back, can convey a lack of self-assuredness. Confidence is often associated with an upright and open posture.

3. Fidgeting: Excessive fidgeting, like tapping fingers, bouncing legs, or playing with hair or clothing, can be a sign of nervousness and lack of confidence.

4. Weak Handshakes: A weak or limp handshake can be perceived as a lack of confidence. A confident handshake is firm but not overly forceful.

5. Crossing Arms: Crossing your arms in front of your body can be interpreted as a defensive posture, suggesting discomfort or lack of confidence in the situation.

6. Speaking Softly or Quickly: Mumbling, speaking in a soft voice, or speaking too quickly can all indicate nervousness and a lack of confidence in one's words or message.

7. Excessive Apologizing: Constantly apologizing for minor things, even when not at fault, can signal a lack of confidence and a fear of judgment.

8. Avoiding Taking Up Space: People lacking confidence may minimize their physical presence by sitting or standing in a way that occupies as little space as possible. This can make them appear less assertive.
