Remember not to let yourself be in a state of tension from time to time. This is not efficient and it is easy to make mistakes. The best state is to set goals, focus on the process and neglect the results;
The book "Scarcity" tells an example of a hospital. A large general hospital has 32 operating rooms, but this hospital has a large number of operations to be done every day, because the hospital’s surgical plan is always It will be disrupted. The doctor always has to work long hours to complete the plan, but the plan still cannot be fulfilled. This hospital is in constant rush, with endless surgical plans every day, and doctors are exhausted because they have to work long hours every day. In order to solve this problem, the hospital has also thought of many ways. For example, the hospital has increased the number of operating rooms from 20 to 32, which is still in this state, because no amount of operating rooms can meet the needs of actual surgery. Later, they found an expert to consult on how to get out of this state. The plan given by the experts after seeing it was a plan of only arranging 31 operating rooms, leaving one room unarranged to deal with emergencies. At first, the dean did not accept the general plan, because the operating room was originally not enough, and now one needs to be reduced. But there is no other way to decide to try this program first. As a result, an operating room was left vacant. When an emergency occurs, the doctor can use the remaining operating room to ensure that other surgical plans are not disrupted and proceed smoothly, because the doctor's surgical efficiency is greatly improved in an orderly state. improve. Leaving a room for surgery without planning and leaving unplanned emergencies solves the hospital’s dilemma.
Why did the hospital get into this predicament before it had prepared an operating room? The explanation of the book "Scarcity" is that when hospitals repeatedly disrupt their plans and are exhausted due to various emergencies, this state is actually a state of "scarcity", in which people's "cognitive bandwidth" changes. It must be very narrow. Under the pressure of completing the task, you can never see anything outside the task (like looking at the outside world through a tube). This state is very energy consuming and very dangerous. We have the experience of driving, we recognize good enough bandwidth than driving 90 yards constant speed oil consumption and safety factor are the best state, while trapped in a "scarcity" state is like opening 140 yards speeding high-speed, fuel consumption and the risk factor Both will be greatly improved.
Everyone has had the experience of speaking on stage. In fact, that state of tension is a state of cognitive “scarcity”. The state of "scarcity" is energy-intensive and cannot last for a long time. Therefore, people who have been in a state of scarcity will be particularly susceptible to "tired" and low efficiency. Moreover, being in a state of scarcity for a long time is particularly dangerous. The book gives an example of the death rate of firefighters. According to statistics, the cause of death of firefighters in the world is not only because of firefighting, but also because of a high proportion of deaths. Various accidents leading to the fire scene resulted in deaths. Among them, a large proportion of them were thrown out of the car and died when they forgot to fasten their seat belts on the road. The reason why the firefighters made such low-level mistakes was actually that the firefighters were caught The state of cognitive scarcity will ignore the important things of peace.

The ways to improve your learning efficiency are:
Memory is the key. Some things need to be remembered, and then the combination of knowledge will gradually form your own thinking and mind. As you have more and more professional knowledge, the combination of knowledge will become more and more abundant. Under the guidance of self-learning mind, the efficiency of learning is naturally high.
About memory
There are short-term memory and long-term memory. Short-term memory can be obtained through repeated reading in a short period of time, but there is a problem that remembers quickly and forgets quickly.
Real learning requires long-term memory. To exercise your long-term memory, there are:
- 1. Retrieval method: After learning the knowledge, put away the materials or books, review the content, and write down the key points.
- 2. Interval learning
- 3. Situational exercises
- 4. Timely self-test
In the above process, it should be noted that "memory" runs through the whole process. Without memory, the above are all blank. At the same time, memory is continuously enhanced in the use of the above methods.
The learning process is very simple:
- Coding: Transform the content of learning in a familiar language
- Consolidation: Repeat the knowledge learned continuously or at intervals to make it form axons
- Retrieval: Retrieval is a tree that connects the axons of each knowledge point, so that all knowledge is connected, so that our memory will be deeper and we will learn more and more.
