What's the best psychological trick?

1. If you want them to consider you an Important Person: If you are in an interview, during a presentation, a meeting or an event, straighten your back and keep your head up.
2. If you want to build trust on your first meeting: copy the poses of the person you're talking to, but be careful, because copying too many poses is not good at all... imitate only small aspects of your interlocutor's posture.
3. If you want to annoy someone: stay calm and silent because there is nothing more irritating than being ignored.
4. If you want to become popular with people: remember your colleagues' names. People instantly feel special when you call them by their first names during a conversation.
5. If you want to make someone feel uncomfortable : Start by staring at the center of their forehead during a conversation. Most people will feel scrutinized.
6. If you want people to say YES to you: when making a request to which you expect an affirmative response, try nodding slightly. This trick is often used by waiters to get customers to buy more food, and it works great.
7. If you want people's respect and admiration: Start sharing stories of your strength and vulnerability. Explain how you achieved success despite countless obstacles. When people start investing time in your story, it means they're starting to respect you.
