1. If you want to know about something from someone

Ask them a question and when they are done answering, keep silent and maintain eye contact. They will tell you some more stuff, almost everything.

2. When you try to convince someone over something

Make sure they are sitting and you are standing. This make.s them believe you sooner.

3.  The key to confidence

is walking into a room and assuming that everyone already likes you.

4. Refer to people you've just met by their name

People love being referred to by their name and it will establish a sense of trust and friendship right away. And continue to repeat the same name throughout the conversation.

5. If someone is attracted to you

Their eyes start blinking more than usual during a conversation with you.

6. Spot the difference between a fake smile and a real one

You can find out if someone is smiling for real or faking it by looking at their eyes. Wrinkles form near the eye corners when the smile is genuine.

7. Pay attention to people's feet

To know if someone is interested in a conversation, look at their feet. If they are pointing towards you, they are interested, and if they are pointing sideways or any other direction, they aren't. Feet don't lie.

8. When at a party or a meeting

When at a party or a meeting, crack a joke and observe the people who are laughing around you. People who feel close to each other will be looking at each other. This is useful for discerning out friendships and other relationships.

9. Make people do what you want them to do

Offer someone a choice instead of a command. For example, instead of saying drink your milk to a toddler, ask which mug would he/she like to drink from. This gives the person a sense of control and produces a higher chance of a better outcome.

10. Win an argument

If the person arguing loses his temper and sharts shouting, natural human tendency is to shout back. DON`T! Stay calm and reply quetly. This will piss them off even more. Try it! It works.

11. Mirror people's body language to build up trust.

If you subtly mimic the body language of the person you are talking to, you can effectively build up trust with them. Mirroring their body language will make them like you more because you will seem more compatible with them.

12. Inception

To plant a seed of idea in someone's mind, ask them not to think of a particular thing at all. Let's say I ask you NOT to think about ELEPHANTS. What are you thinking of?
