In order not to be conspicuous, Wang Jian sells more than a dozen servings of fried chicken every day, and these fried chickens that use many excellent spices can be said to have quickly conquered the rich people in the slums of the secret realm, which is easy to understand, no matter how poor the place there are rich people, and no matter how rich the place is there are poor people.

Something, once it is missing, will be attached to a cherished aura.

Soon Wang Jian noticed that the owners or cooks of several shops must be secretly experimenting with how to make such fried chicken.

But they lack the material base, which is the spices, the oils, and the starches.

Needless to say, spices are all products and imported products after these people in the secret realm escaped to the secret realm.

Fat is transformed by extremely precious food, so to speak, it is not an extremely extravagant person, where will use food to squeeze oil.

The best oil extraction technology is about five catties of soybeans and one catty of oil, and it is not guaranteed that all of them are like this.

Five catties of beans can be used for an adult, plus multigrain and wild vegetables for half a month!

Therefore, even if the oil extraction technology has long been available, this thing still cannot be promoted, and no one will support this extravagance, as is the case with starch.

Therefore, when going to a new place, Wang Jian's favorite places to observe are three places.

Taxi, library, restaurant.

Taxis can show the economic strength of a place, as well as social security, if taxi drivers like to pit people to take a long road, then the local security, certainly not good.

Whether there are many people reading books in the library is also related to the quality of the people in this place.

The museum can see the quality of life of the people here, understand these three places, and basically have everything in the local hands.

In this regard, Wang Jian's observation is also quite sharp and accurate.

What is the cost of trial and error?

For a person, the cost of trial and error refers to the cost of failure in the process of doing an uncertain thing, choosing an industry or job.

This cost can be time, it can be your effort, or it can be money. Reducing the cost of trial and error sounds like a mystery, but it's actually very simple, it's about choosing something that gets it right and making it as successful as possible. It requires a person to have a unique vision and insight, know what he is good at, and know what he can do as soon as he does it. In addition to that, you have to keep persevering, put in absolute effort, and use all kinds of resources to make it well.

What is the opportunity cost? In a nutshell, it is the amount of benefit that you may bring from giving up other choices for the sake of one choice, and this benefit is your opportunity cost. The choice cost is the cost you incur in order to make the choice decision, and the opportunity cost is the cost that comes after you make the decision. Take buying a house as an example, during the decision-making period, you choose more than a dozen real estate projects in two months, and all the costs caused by doing these work are your selection costs; in the end, you choose a real estate and buy a house of one million, at this time, your opportunity cost will appear. You only have this million in your hand, you can buy a house, you can also invest, you can also deposit in the bank, but the income of each choice is not the same, buying a house may not increase in value for ten years, but the investment may earn another 500,000 in three years, buying a house is equivalent to giving up the 500,000; but if you don't buy a house, you can only rent a house, renting a house will make you not rest well and can't go to work wholeheartedly, this job can bring you at least 200,000 income every year, so if you don't buy a house, you will lose this job. So, your opportunity cost is the amount of 500,000 you earn by investing or losing a job that earns 200,000 a year.

At this time, what decides whether you buy a house or not should not be the value of the house, but your investment income or your job, if you feel that the job is very important, then the house should be bought even if it is not worth 500,000 yuan, because you are buying your future job; if you want to get the income from the investment, then the house value should not be bought even if the value is more than 500,000 yuan, because you don't know what opportunities you will encounter and how much money you can earn after you have 1 million in three years.

Talking about this, everyone should be able to understand what the opportunity cost is, in fact, the opportunity cost accounts for a large proportion of another one, called the cost of trial and error, the cost of trial and error is that when you are faced with multiple choices, it is very likely that your first choice is wrong, and the loss caused by this mistake is the cost of your trial and error. Everyone should have shopped online, sometimes we urgently need a thing, for example, you interviewed for a job, the boss informed you to come to work the day after tomorrow, but you will not have professional clothes, and it is too expensive to buy offline, so you bought a set online, and spent money to send SF, wait, wait, and finally received it the next day, after receiving it, you found that the size of this family's clothes is not right, usually you wear 4XL size, but this family's 4XL size is too small, you can't wear it, you want to change it, it's too late, no way, you can only return the clothes and run down the line to buy a set of very expensive, at this time you don't seem to have any loss, but, if you don't buy onlineIn fact, you have two days to go to various offline stores to choose, and you may still be able to buy very cheap ones, but now you don't have time to choose, and your large body type is not easy to find a size, you can only hurry up and buy a set, as long as the size is right, you can't take care of the price, and even worse, you can't find the right size, this job says goodbye to you. So it seems that you buy a set on Taobao very cheaply, but these problems that may cause you will cause an increase in costs, and these problems that may cause more expensive problems and problems of losing your job are all the costs of your trial and error.

In many cases, the opportunity cost, the cost of trial and error is actually very large, in order to avoid these mistakes, you can only pay more to avoid this cost; look at the big picture, when a company is faced with two customers are likely to sign a contract, you must try to keep both customers, you can only use more resources to retain these two customers, and can not put resources on a customer, these two opportunities are very important, you have no opportunity for trial and error, once you miss it, there will be no more. A critically ill person, you can only choose the best medical service for him, you can't go to one by one to try whether the folk remedies are useful, once it is useless, you will miss the best time to treat the disease, delay the condition, and even cause an irreparable situation. In the face of these choices, you can only devote more resources to avoid mistakes and missed opportunities.

Everything you pay for a choice before you make a choice decision is the cost of your choice.

In daily life and work, we often need to make choices, from clothing and food, to work and buy a house, we are faced with countless choices every day, but we actually ignore a problem, that is, each of our choices has a cost.

Buying a house is a big deal for most people, everyone will carefully select back and forth comparison, and finally make a decision; before you make a decision, you go to the various real estate to see the house, find information comparison, find someone to consult, and discuss with your family, in this process, you spend time, manpower, material resources, brain power are your choice of cost, you may choose a better school district house back and forth to see more than a dozen real estate, run no less than 100 kilometers away, you then buy a house to pick the location, pick the developer, pick the property, Before you make the decision to pay, you will always think about this in your mind, and he will always occupy a certain bandwidth in your mind, even if you are working, this string in your mind has been tightened, and this matter will always affect your mood and state.

We will face choices in life, and we often face choices in our work, when the company recruits people for interviews, you can interview a hundred people, pick out an elite from these hundred people, and interview another ninety-nine people. Labor cost is the cost of your choice of employing this person; you need to analyze and study your customer to decide what kind of service plan to provide him, and all the costs incurred in the process of analysis and research are the cost of your choice of this program; you need to purchase a batch of equipment, and coordinate the purchase process with a number of suppliers to study, determine the equipment model, and coordinate and confirm the time and cost you spend in the process of confirmation.

Since there is a cost to choice, then this cost can be quantified and reduced

So how to reduce the cost of our choice? Take the clothes and shoes we usually buy as an example, how do we buy clothes under normal circumstances? First go to the mall or Taobao to go around, after a day of shopping, I didn't find what I liked, either it was too expensive, or I didn't like it; or I was really tired of looking at it all day, so I chose one at random, and I found that there was no other clothes to match with this one, and you had to go to match this new dress with a set of outfits, originally I just needed to buy a pair of pants, but I bought a whole set with clothes and shoes, and it was useless to buy it back. In the whole process, not only wasted time, but also wasted energy, and finally took two days off work, and one day shopping was more tiring than going to work. The problem of this choice cost is actually very easy to solve. The solution is that you stare at a brand and buy it.

The "cost of trial and error" is the cost of a process of trial and error. There is a cost of trial and error in national development, trial and error cost in human development, trial and error cost in enterprise development, and trial and error cost in personal career planning. The future is full of hope, but it also requires our own trial and error.

It takes courage to make mistakes, because if you make a mistake, you will need time, money, or something of equal value to pay for it. The progress of mankind has always been inseparable from continuous trial and error, and it is summarized and grown in trial and error. We would like to thank the sages and predecessors for trying many "mistakes" for us, because with their attempts, the latecomers have avoided detours. Without Shennong's taste of herbs, perhaps there would have been no advent of medicine, without Cai Lun's papermaking, we might still be writing on bamboo, and without Edison's invention of the electric light, it is estimated that we would still be reading and writing with candles. This is not alarmism, but fact.

The process of growing up is actually continuous trial and error, only when you have seen the worst experience, can you learn to enjoy the good, and only after experiencing mistakes, can you learn to look at life. From the first day we set foot in society, we have to pay for every trial and error. "Standing at the age of 30" before the age of 30 is an important stage for learning and enriching oneself, establishing one's own values, outlook on life, attitude and principles towards life. Twenty-something is the age when you have no ambitions, but you have nothing.

"Trial and error" is the only way to grow, and it is also a problem that will inevitably be encountered in the process of self-dialectic.

We must dare to make mistakes and learn to make mistakes, one is conducive to promoting our own growth, and the other is to verify our own ability.

Many people choose to go the safe and conservative way because they are afraid of failure or cannot afford to fail. It is no exaggeration to say that this is the biggest failure. Because this will lead to the loss of opportunities for growth, and at the same time, it will lead to eternal doubts about oneself (without proof, you will not be able to understand your true self, it will be difficult to have a sense of accomplishment, and it will be difficult to generate self-confidence), and the ability to lose growth opportunities will be stagnant, and you will hesitate to believe in yourself. So you have to go through trial and error.

In order to gain effective experience at the lowest cost, and in order to maintain the security perimeter. We need to calculate the cost of trial and error and keep the bottom line of making mistakes! How to obtain effective experience and maintain the safety boundary at the lowest cost? We must learn to "build theoretical models and do low-cost experiments"!

In fact, to do any similar thing, no matter how big or small, its basic model is almost the same, and the so-called sparrow is small and has all kinds of organs.

Just like doing business, the model behind any business is the same. It should all involve: products, brands, channels, marketing, services, and management.

Therefore, if we want to do experiments in business, we must first build this theoretical model. Even if you are doing a small business, you should follow this model, so that you can quickly build this logical framework, and at the same time, you can effectively evaluate your ability in these aspects in the process of implementation.

In this way, you will be able to master the basic theoretical methods of doing business through experimentation, as well as discover the scope of your abilities. Many people like to blindly try and make mistakes, which leads to failure. I don't know how to build a theoretical model, so I don't get anything out of it.

The fundamental reason for low learning efficiency and low work efficiency is that there is no systematic theoretical framework and no learning to do experiments. Without a systematic theoretical model, you can't find problems, and if you don't have experiments, you can't discover your own capabilities. Therefore, it is very necessary to grasp this idea.

There are still some people in life who are willing to try and make mistakes, not because they have more time and energy, but because they want to prove whether what they think is correct. Trial and error requires courage and charm, and the wrong choice of any thing will have a certain loss, in the process of trial and error in this causal cycle, they gradually learn to take responsibility, have courage, and understand the sense of responsibility.

The same road, turning from the first intersection and turning to the second intersection, the result is not the same, when you turn at the first intersection, maybe the first intersection is correct, but you hesitate, you go to the second intersection to turn, the second intersection is wrong, it will be far away from the goal, but you have already turned, you can only go to trial and error, and then pay the price, the result is that the second road deviates from the goal, it is wrong, you have an invisible trial and error that makes you know that you can only turn from the first intersection in the future, not the second, which is not a good thing
