It's not too late to find three signs that a person is beginning to become stupid before the age of 30.

Professor Yang of Fudan University once said: When a college student leaves the university after graduation, 50% of the knowledge he has learned in these four years is outdated.

In addition to innate conditions and knowledge base, what separates people is a more important quality-the ubiquitous "working memory" in life.

The three most helpless moments of collapse in daily life are all related to this.

First, inexplicable forgetfulness

You must have walked from room to room and suddenly forgot what you just wanted to do.

Ready to go out, can't remember where the key is, half a day, only to find that it has been stuffed into his pocket. ...

These signs do not mean that a person's memory has deteriorated, but that he has no sense of "processing" from the beginning.

The idea of "finishing" can not only help us manage our own lives, but also help us manage our own thoughts.

For most young people, when they first enter the workplace, they will always encounter all kinds of chaos: one job after another, endless demands for new skills, and communication and cooperation between departments. ...

Some people describe their work like this: "Every Monday, opening a work mailbox feels like opening a door full of things, and all the things in it hit your head instantly ..."

What is true and sad is that if something really hits you, most people will sort it out immediately.

Naturally, put the heavy things below, the light things above, the commonly used ones at a moderate height, and throw away the ones that will never be used. ...

However, most people choose to "temporarily" shelve their work tasks and massive information.

"Working memory" is a concept in cognitive psychology, which refers to the temporary storage of information and the joint operation with other more complex tasks.

The way of receiving information determines the degree of understanding information, and the size of this ability also determines a person's intelligence to a certain extent.

People with strong working memory perform better in writing and exams.

People's working memory capacity is different, and this ability will change with time. When young, before the age of 30, the capacity showed an upward trend; After middle age, people will gradually decline.

Educator Peter Doolittle gave a talk at TED called How Your Working Memory Understands the World. In his view, "the ability of' working memory' allows us to balance what we just know and what we have already remembered, and finally let us meet the current needs.

To organize knowledge, it is necessary to mobilize old memories in the brain until new information is useful to us. This' assembly' process can only help us learn something and prove the meaning of our existence. "

If we don't pay attention to the process of assembly and arrangement, we will be no different from the walking dead.

What tasks are the most important, what can be shelved first, and which tasks are helpful for career development?

Respond in time and deal with it in time. I don't want to put them in a "working memory" like a workbench, but I want to deal with them later.

Over time, more and more new information will not be remembered, nor will it be associated with existing knowledge.

Each task has its own attributes, just like the weight of an item, which determines where we should put it in the work cabinet.

In the workplace or life, the purpose of doing anything is not only to complete things, but to exercise ourselves and improve our cognitive ability to the world.

Second, it is impossible to fight against the inertia cycle.

Setbacks in life are far more than forgetfulness.

When I was a child, I was crushed by a schoolmaster who looked completely "not working hard". At work, I am too eager to do what others can easily do.

Perhaps innate qualifications are one thing, but in the long-distance running of life and work, "learning ability" plays an important role. It can always bring people new ideological heights.

For example, twenty years ago, no one would have thought that a person could become an online celebrity because he was proficient in makeup; Because you can write "paragraphs", you can become a "traffic manager" in the Internet world.

There is always a person who can sum up a set of "knowledge" for everything you are not surprised about in life. You who were not interested in that matter will be attracted by the truth.

"As long as you know what others don't know and say what others won't say, you can gain an audience through sharing."

When we become an audience, it is easy to fall into this anxiety caused by sharing: "Why do they have so much to share and I don't?"

You need to consciously build a knowledge system.

This is an extremely important ability in today's society. The key is not the system itself, but the process of construction.

There are four steps to internalize complex knowledge:

1, starting with "I"

Just because you learn new knowledge without hesitation doesn't necessarily mean that you are a "smart young man".

There is so much knowledge in the world, some are beneficial to us, and some are not so beneficial to us. Learning this knowledge is not necessarily harmful, but it will take up time and energy and make us unable to get more useful information.

This effect is called "opportunity cost" in economics.

Li Ao once wrote an article entitled "Election and Failure" to discuss this choice:

"... your life is so short that it is not enough to deal with what you choose all your life; It is not enough to be a person who can only do it all his life.

Giving a part of your life to others-past, present and future-is a waste of life. "

When choosing the knowledge I want to learn, I should also think: Is this what I should learn most at this stage? If not, what is it?

The first thing you have to do is to find your own field, and then make all efforts around this field.

2. Related to "I"

After choosing knowledge, we should further evaluate the significance of new knowledge to ourselves in our study.

Feasible problem framework;

(1) What are the similarities or differences between the new knowledge and your previous views?

(2) What concepts have new knowledge supplemented or changed?

(3) in the future, what opportunities will you have to apply this knowledge to yourself and solve what problems?

Thinking about these questions is equivalent to marking the position of new knowledge on the coordinate axis: what have they changed me? What can help me change the future?

Step 3 build a structure

After completing the above two steps, you can reorganize the mind map in your brain.

Clarify the internal logic between knowledge, create clues between knowledge, and help us to recall when using knowledge.

The extraction of human memory needs clues. Just like the memory palace mentioned in the English drama Sherlock, what we forget is probably not really forgotten, but we can't recall it because of lack of clues.

Depending on a street or a house, multiple concepts can be divided into modules with logical relationship, and the concept ladder can be increased and the number of concepts on each ladder can be reduced.

Although you have learned more knowledge, it will be easier to remember when the knowledge has established internal relations.

Step 4 practice in time

After forming your own knowledge system, the most important thing is to practice knowledge in time.

In a review in the field of learning psychology published on 20 13, the researchers summarized the results of more than 100 empirical studies and 10 learning methods commonly used in school education, and found that the learning effect combined with practice is the best.

From the beginning, we should think about how to internalize this knowledge into our way of thinking, way of doing things and even our vision and pattern.

In this way, this seemingly innocuous and difficult information point can guide life.

Third, I don't understand the controllability of life.

Faced with a mess, I can't think of a solution, not so much because of the impermanence of life as because I don't make good use of the power of thinking.

In fact, many times, we are not really alive.

We didn't realize, we didn't think, we didn't deal with it, we just let life flow through us and even engulf us.

The middle line of the movie Beyond says, "Our helplessness is like drifting on the sea. No life jacket, no sense of security. Suddenly you suddenly realize that it was you and threw away your life jacket. "

When you are at a loss, try to find that life jacket-screening, thinking and constructing.

We should be the masters of our own lives, and the way to be masters is to understand life, choose life, organize and build our own lives and interpret the unique significance of each event to ourselves.

At present, no young people face the problem that they can't have both. Many times, what we can see are all options with their own advantages and disadvantages, just like a Manchu-Chinese banquet.

Choose what you want and take it seriously; Abandon those who have not been selected, and no longer show nostalgia and hesitation.

It is a minefield that every young person should avoid, which is not more and more ignorant, but more and more stupid.
