If you are not confident, she will know. A lack of confidence is a huge turn-off to most women. So how do you display your confidence? Project confidence by looking into her eyes and standing or sitting upright, with your shoulders back rather than hunched. Don’t let your voice go up an octave, which is common to all people when they’re nervous. Make your gestures slow and deliberate. The more confident you are, the less likely you will be rejected.
