Smart people come in, and what kind of people are smart at first glance

Don't be confused!

Help you clear your mind:

We can divide these people into two parts, the giver and the receiver.

The payer is three students, 90 yuan per person, a total of 270 yuan.

The money collector was the shopkeeper and the shopkeeper, and they received 250 yuan and 20 yuan respectively.

Therefore, when this amount of money is in and out, it is equal to the amount, and there is no change at all.

And one of the errors in your algorithm is that the original students paid 100 yuan each, and then they found 10 yuan per person, so they actually only paid 90 yuan per person, and the students' accounts were fine.

And the total amount of money is 270 yuan, but you add up the 20 yuan and 270 yuan of the shopkeeper, one of the receivers, it is obvious that such a result does not have a clear meaning at all. And if you use 270-20=250, you will get 250 yuan from the other shopkeeper. Do you understand?

The three students paid a total of 300 yuan, the boss returned 50, and the three students should have only paid 250Xiao Er took 20 from three students, so the three students paid 270 yuan, plus 30 yuan, isn't it 300 yuan?

The two have nothing to do with each other, and the twenty of the second child is in 270.

Don't complicate the problem: 300-50-20 (Xiao Er took it) = 30 (10 yuan per person).

The 20 yuan that Xiao Er took was regarded as the room fee, and the three students consumed it, that is to say, they spent a total of 270 yuan on the room fee, and then added another 10 yuan each of them, which was exactly 300 yuan. The $20 is included in $270.

It should be that the three students paid 270 yuan, and the boss took 250 yuan, and the second child took 20 yuan. And 300 yuan should be 250 yuan for the boss + 20 yuan for the second child + 10 yuan for each person * 3 students.

270 20 290, three students came out with this money, and 10 yuan did not exist.

The two simply don't matter.

All the people who seem to be smart, have paid for their "cleverness" that you don't know about.

Feature 1: Good at applying what you have learned.

Like any "tool" we use on a daily basis, we need to use it a lot before we can enter the "proficient" stage, and then we can "use it freely".

But ordinary people only stay at the level of "knowing", while smart people will try to make themselves "do".

Feature 2: Long-term vision.

When they do something, they will not only look at short-term gains, but also look at whether there are development opportunities or value-added space in the long run.

To get rid of the thinking limitations of simple linear extrapolation, the key is that you don't think about the future according to the current state of things, but know that every action and decision you make now will have a butterfly effect on the future.

Feature 3: Good at creating win-win or multi-win opportunities.

They understand that the essence of networking is value exchange, if your value is low, no matter how good the relationship will eventually dissipate, only the value is equal, there will be a chance to exchange.

So they're always asking themselves:

What kind of value can I create for others?

How can I help others achieve their goals?

Feature 4: Good at discovering the essence of things.

They will spend more time studying the laws behind things, or Su will find the essence of the problem, start from the rules, and solve the problem more efficiently.

Feature 5: Good at reflection and review.

They know that if something doesn't get the result you want, it must be that the conditions are not enough. Therefore, in case of trouble, we must first analyze what conditions need to be met for the achievement of this matter.

Feature 6: Pay attention to the breadth and depth of the industry.

The breadth of the industry is the knowledge side: do you understand the core technology, peripheral technology, and knowledge related to the industry, including what is the change of one point for the change of other points? The understanding of the connection of all related knowledge planes is called breadth.

What is industry depth? Including understanding how many core enterprises there are in this industry, what are the core characteristics of each of them, who are the main operators of all core enterprises, whether you have intersection with these people, your intersection with him, whether you have met or know each other, he will ask for your views on some issues, and what level of issues he will ask for your views on what level of issues, this is the depth of the industry.

People who have bright eyes, love to laugh, have strong understanding skills, speak and act steadily, and are very smart.

People who look silly, but often follow others to speak, make people sound particularly comfortable.

His eyes were bright, his forehead was bulging, and he was very energetic, as if he was about to blurt out words.

Someone who can talk, open her mouth to know if she is smart or not.
