These are psychological tricks work on most people

When you first meet someone, make note of their eye color.

This isn’t because their eye color is important, but by taking a moment to look and make note of it, you will be giving the perfect amount of eye contact. We all know eye contact is important in social situations. Too much is creepy and uncomfortable, and not enough makes us seem shifty and untrustworthy.

3. Match body language.

Mirroring someone’s body language is an effective way to gain rapport. Don’t overdo it in a distracting way, but subtly assume the same overall body postures. A person who stands at a distance with his arms crossed is less likely to feel comfortable with someone who stands close and uses broad open arm gestures.

Use a person's name right away.

I forget names the instant I’m introduced to someone. It’s terrible. Experts recommend using the person’s name a couple of times right away to reinforce it in your mind. This has an added benefit of making the person like you more! People like to hear their name. It makes us feel important.
