Adjust your posture. The way you hold yourself and move around plays a big role in determining your mood and how others see you. Make it a habit to sit and stand with your back straight and your shoulders back. Distribute your weight evenly and tighten your abdominal muscles.
Make eye contact. Hold your head and your gaze up. If you find it uncomfortable to look someone in the eye, try focusing on different areas of their face for a couple of seconds at a time. The results will be about the same.
Open up. Overall, think in terms of taking up whatever space is available to you. Uncross your arms and legs. Plant your feet about a foot apart. Lean toward someone while they’re talking to you.
Slow down. If you tend to move faster when you’re nervous, experiment with doing the opposite. Make your gestures and speech more deliberate and relaxed.
Smile wide. A happy face looks more confident and attractive. Think about how you feel when someone beams at you and share that joy with others.
