1. Primacy and recency : People most remember the first and last things to occur, and barely the middle.
When scheduling an interview, ask what times the employer is interviewing and try to be first or last.
2. If you work in a bar or in customer service of any kind…
…Put a mirror behind you at the counter. This way angry customers who approach you will have to see themselves in the mirror behind you and the chances of them behaving irrationally lowers significantly.
3. Once you make the sales pitch, don’t say anything else.
This works in sales, but it can also be applied in other ways. My boss at an old job was training me and just giving me pointers. I was working at a gym trying to sell memberships. He told me that once I got all the small talk out of the way and presented the prices, that the first person to talk will lose. It didn’t seem like a big deal but it actually worked. Often there were long periods of awkward silence as the person tried to come up with some excuse, but usually they bought.
4. If you ask someone a question and they only partially answer, just wait.
If you stay silent and keep eye contact they will usually continue talking.
5. Chew gum when you’re approaching a situation that would make you nervous like public speaking or bungee jumping.
If we are eating , something in our brain reasons ‘I would not be eating if I were danger. So I’m not in danger’. It has helped me to stay calm a few times.
6. People will always remember not what you said but how you made them feel.
Also most people like talking about themselves so ask lots of questions about them.
7. When you’re learning something new, teach it to a friend . Let them ask questions to you related to it.
If you’re able to teach something well, you can be sure that you’ve understood it very well.
8. If you get yourself to be really happy and excited to see other people, they will react the same to you.
It doesn’t always happen the first time, but it will definitely happen next time.
9. The physical effects of stress – breathing rate and heart rate – are almost identical to the physical effects of courage.
When your feeling stressed from any situation immediately reframe it : Your body is getting ready to be courageous, it will NOT feeling stressed.
10. Pay attention to people’s feet.
If you approach two people in the middle of a conversation, and they only turn their torsos and not their feet, they don’t want you to join in the conversation. Similarly if you are in a conversation with a coworker who you think is paying attention to you and their torso is turned towards you but their feet are facing in another direction, they want the conversation to end.
11. Fake it till you make it ; confidence is more important than knowledge.
Don’t be intimidated by anyone, everyone is playing a role and wearing a mask.
12. If you pretend to be something for long enough, you will eventually become it.
13. Not to be creepy, but if you want to stare at someone unashamedly, look directly past them and wait for them to try and meet your eyes.
When they fail to do that, they’ll look around (usually nervously for a second) they won’t look at you again for some time. This is your chance to straight up stare at this person for at least 45 seconds.
14. Build a network.
Become their information source, and let them be yours. Even grabbing a beer with a former colleague once a year will keep you in the loop at the old office. Former coworkers might have gotten a new position in that office you always wanted to work in, great! Go to them for a beer, and ask about the office. It’s all about connections and information.
15. If you are angry at the person in front of you driving like a grandmother…
Pretend it is your grandmother, it will significantly reduce your road rage
16. Stand up straight
No slouching, hands out of pockets, and head held up high. It’s not just a cliche — you literally feel better and people around you feel more confident in you.
17. Avoid saying “I think,” and “I believe” unless absolutely necessary.
These are phrases that do not evoke confidence, and will literally do you no good.
18. When feeling anxious, clean up your home or work space.
You will feel happier and more accomplished than before.
19. Always buy the first pitcher or round of drinks.
You’d be surprised how long you can drink on the phrase “I bought the first one.”
20. Going into an interview…be interested in your interviewers.
If you focus on learning about them you seem more interesting and dynamic. (Again, people love to talk about themselves.)
21. Pay Attention Parents: Always give your kid a choice that makes them think they are in control.
For instance when I want him to put his shoes on I will say ,”do you want to put your star wars shoes on or your shark shoes on?”
Pro-tip: In some cases, this works on adults.
22. Your action affect your attitudes more than your attitudes affect your actions.
As my former teacher said “You can jump and dance FOR joy, but you can also jump and dance yourself joyful.”
23. When a group of people laugh, people will instinctively look at the person they feel closest to in that group.
24. If you want to build rapport or gain someone’s trust quickly, match their body posture and position.
If someone is sitting with her legs crossed cross your legs. If they’re leaning away from you lean away from them. If they’re leaning towards you, lean towards them. Mirroring and matching body position is a subconscious way to tell if someone trusts you or is comfortable with you. If you’re sitting with your arms crossed and you notice someone else is sitting with her arms crossed, that is a good indicator that you have/are successfully built/building rapport with that person.
25. The Benjamin Franklin Effect (suggested by Matt Miller)
The pencil one may seem far-fetched but I find the basis of it (the Benjamin Franklin effect) is very useful and extends far beyond pencil borrowing. This knowledge is useful in the world of flirting too. Asking a girl in your class if you can borrow a pencil or her notes or to explain the homework will make her more likely to like you than if you let her borrow your stuff or are the one to help her. Even just asking a girl to buy you drinks (facetiously) leaves a much bigger impression than offering to or actually buying a girl a drink. The best part is it kills 3 birds with one stone: you get the advantages of the favor itself, the person subconsciously likes you more, and it makes them more open to future favors and conversation.

附：
这篇回答在Quora获得一万多赞。我读过之后，也觉得收益良多。
简译如下：
1、人们倾向于记住最先发生的事情和最后发生的事情。中间的事情记不清楚。所以，如果你要做自我介绍的话，最好做第一个或者最后一个。面试的时候，也是一样的。
2、如果你在酒吧或者前台工作，在你身后放一面镜子。这样的话，当顾客发脾气的时候，就能从镜子里看到自己的丑恶嘴脸。一面镜子可以显着降低他们无理取闹的概率。
3、报价之后，不再说话。如果你是做销售工作的，这项技巧很有用。在其他领域，这项技巧也很有用。我之前干过一份工作，是在一家体育馆卖会员卡。有个老家伙就是这么指导我的，他说，一旦你和顾客寒暄完毕，报出了你的价格。从此时开始，先开口的那个就输了。看起来好像毫无根据，但确实是这个样子的。通常会有很长时间的尴尬沉默，但是，最终，顾客会买的。
4、如果你问了别人一个问题，然后他们回答了一半，你等着，他们会说完的。只要等着，保持眼神接触，最终，他们会开口讲完的。
5、公开讲话或者蹦极之前这种会紧张的时刻，嚼口香糖就好了。据说是因为人类在危险的时候会自动停止咀嚼（吃东西），所以吃东西的时候就是安全的，大脑就是这么告诉你的。反正这招对我很管用。
6、人们最终记住的不是你说过的话，而是你让他们产生的感觉。几乎所有的人都喜欢谈论自己的事情，所以，多问问题。
7、当你学习新东西的时候，尝试着教给朋友们，或者让他们问你相关的问题。如果你能教给人一杯水，你自己一定会有一桶水。
8、如果你看到某人时，很开心，溢于言表的开心，那么他们以后看到你也会手舞足蹈的。第一次也许不是这样，但第二次一定是。
9、身体对压力的反应——呼吸加速，心跳加快——和鼓起勇气时的反应是一样的。所以是好是歹，全在你一念之间。反正你的身体已经都准备好了，你看着办吧。
10、注意别人的脚。当你加入别人的谈话时，发现别人只是把上半身转过来了，脚还是维持原来的方向，那就说明他们不欢迎你的加入。类似的，你和你的同事谈话时，你觉得他在专心和你谈话，他的身体也面向你，但他的脚却不是朝向你的，他可能早就已经受不了这场谈话了。
11、装出牛逼的样子，直到你做到了；信心比知道更重要。别被任何人吓住，生活不易，全靠演技，那些吓你的人也在演戏。
12、你假装成什么样子，你最终就会成为什么样子。装逼得逼，求仁成仁，念念不忘，必有回响。
13、虽然不是要你去吓人，但如果你一定要厚颜无耻的盯着某人，视线聚集在他的两只眼睛中间，等着他们害羞。(www.lz13.cn)如果他们移开视线，他们就不会再看着你。这个时候，你就可以肆无忌惮的盯着他们的眼睛了。至少有45秒的时间哦。
14、建立人际网络。成为朋友们的信息源，当然，他们也会是你的信息源。和前同事一起喝杯酒吧，也是好的。
15、如果你前面的车子慢的像是老爷爷在开，你恨不得杀了他。假装他真的是你的亲爷爷。 然后你的怒气就全消了。
16、站得直。 不许没精打采，不许手插兜，头要高高抬起。不要觉得这是陈词滥调。你自己会因此觉得很好，而且周围的人也会感受到你的自信。
17、不要说“我觉得”、“我认为”，除非真的有必要。这些词语会让你和自信无缘，对你可没什么好处。
18、焦虑的时候，收拾一下家里或者工作桌。你会比之前更开心、更有感觉。
19、第一次饭，第一支酒，你请。你都不知道你自己会因此而自我感觉良好多久。
20、为人父母者请注意：给孩子们选择的权利，让他们认为自己掌控自己的生活。比如我想让孩子自己穿鞋的时候，我会问他“你是想穿那双星星的，还是鲨鱼的？”。值得注意的是，这招对成年人也管用。
21、态度决定行动，可是行动也决定态度。就像我以前的一个老师说的那样：你可以因为高兴而跳起舞来，也可以故意跳起舞来让自己高兴。
22、一群人在大笑的时候，人们会立刻看向这群人里最亲近的人。
23、如果你想和某人建立密切的关系，或者获得某人的信任，学习他的身体的姿势。
24、本杰明·富兰克林效应。借给别人钱的人会比欠别人钱的记得更清楚，而且会不由自主地对借贷者产生好感。调情的时候也很有用。“同学，借我一根铅笔”。或者开玩笑似的让女孩请你喝支酒。这可是一石三鸟的事情：你得到了好处；她会下意识的更喜欢你；将来她接受你的“帮助”也会更加没有负担。
