Generally speaking, it is: those who are close to Zhu are red, and those who are close to ink are black.

Therefore, if you want to know a person, especially when choosing someone who needs long-term communication and cooperation, you can basically judge the level of this person by looking at his five closest friends.

In fact, this is an extension of Matthew effect, which can also be explained as the influence of environment on people. Excellent people, because they are excellent, will focus on the same excellent people around them; And excellent people get together, which in turn promotes their progress together, thus forming a virtuous circle.

Conversely, the vicious circle is also established in this way. Discuss this view in Why I suggest you go to a good school.

However, in this cycle, the most critical thing is not the environment, but "whether you can make continuous progress". Because once you fall behind, you will be out of the virtuous circle. Therefore, getting along with excellent people does not mean that we can relax ourselves and feel that it is an average anyway, so I just wait for others to share it with me.

Being excellent and becoming excellent are not once and for all. We should remind ourselves that if we don't advance, we will fall back.

2. Opportunity cost principle: If you decide to hang yourself on a tree, you have to give up the whole forest.

What this sentence emphasizes is "don't be obsessed."

Nowadays, in the workplace, even in Japan, life-long employment is not advocated. It is very rare to work in a company for ten years. Not only do individuals need more space, but companies also need fresh blood.

Whether you choose a company, a boss, a friend or a lover, don't be obsessed.

A small company, a boss in cheat people, a bad friend or a lover with different views should make a choice.

What many people lack is not the capital of success, but the courage to choose.

3. Festinger principle: If you make a mistake, you need to do nine correct things to correct it.

The complete explanation is: in a person's life, 10% is made up of what happened to him, and the other 90% comes from his handling of this matter, that is, his actions afterwards. Therefore, if a person makes a mistake in interpersonal relationship, he needs to do nine correct things to correct it.

For example:

You said something you shouldn't have said on a certain occasion, so you offended the leader. If you want to repair the relationship between you and the leader and change the negative impact of this mistake, you have to do something to make other leaders present at that time stop thinking about you and work harder.

Although it won't be dismissed immediately, the bad impression itself is a thorn. As long as you don't pull it out, it will be somewhat responsive.

This means that frequent mistakes and make-up mistakes will actually make you go further and further on the wrong road, and the pit will grow bigger and bigger.

Therefore, the best way is to put an end to the first wrong start.

The most important thing to control the first mistake is to control emotions. Impulse is the devil, that's what I mean.

4. six degrees of separation Principle: There are only six people between you and anyone in the world at most.

In other words, you can meet any stranger, your idol or leader through up to five intermediaries.

This theory is derived from the model, let alone whether we will really contact our idols. The establishment of this theory can bring us a lot of imagination in social life.

5, the principle of reciprocity: give a rose, leave a lingering fragrance in your hand.

Many times, it seems that we have not gained anything by helping others. We are the paying party, but in fact, the "good impression" you have saved is likely to help you at a critical moment.

Because people who receive help usually have a sense of debt, which is not felt at first, and it will be obvious from little to more.

For example: usually praise bloggers, bloggers will feel indebted when they receive encouragement and help, and then return with better content.

6, the principle of diminishing marginal utility: no matter how good the milk tea is, there is also a greasy day.

I don't know if you have this experience: I haven't drunk milk tea for half a year, and finally I have the first cup and feel like I am in heaven; The second cup, not bad, still satisfied; The third cup, ok, is the taste of milk tea; The fourth cup, the fifth cup ... slowly you will lose your feeling, and even feel worse than boiled water, at least you won't gain weight.

Today we joked in the office:

I didn't go to work for more than 80 days, and when I came to the office on the first day after I was approved, I really missed it. Sitting before I went to work, I changed from a notebook to a desktop, which made people feel a sense of ritual, and the whole day was efficient enough to fly.

The first week was exciting, the second week was calm, and by the third week, it was no different from everyone who had been to work. It was still from the first second when I stepped into the office, and I counted down when I could get off work. It's still that colleagues who are constantly discussing problems in the office are noisy and even have a bad rest at noon ...

This phenomenon, citing the concept of economics, is called diminishing marginal utility.

Doing the same thing and saying the same thing for a long time will make people feel bored, that is, the freshness will be reduced.
