Do you think there will be a free lunch in the world?

Yes! Isn't that what our mom cooks?

There really is no such thing as a free lunch. If you eat this free lunch, then you will definitely lose some value in a place or thing.

When you are eating this free lunch, you miss a scratch chance to win a prize, and this ticket can be hung out for more than 100 prizes, at which point 100 prizes are your opportunity cost.

I think everyone has heard of pie falling from the sky. I'm not afraid that pies can also kill people. Be a man, it's better not to be greedy, otherwise you will suffer a big loss sooner or later!

When you understand the opportunity cost and apply it in your own life, you will gain the initiative in some games, so that you can have more opportunities and be more efficient. Opportunity cost can not only be used in the field of economics, but also can produce results in life and other fields, through which you can have better choices to show you.

There is a free lunch in the world, when we were young, every time after school at noon, my parents would bring the hot meal to the table and watch us gobble it up with a concerned face.

Security issues, free lunch, how do you know if something will be added to it? Personal safety cannot be guaranteed. Eating a bad stomach is small, and eating a big thing is not good.

There is a cost to your choice, don't try it, because you are trying at the cost of losing other opportunities, and you must try to get a worthwhile result.

Everyone has a different opinion, for example, today a certain park is open for free for half a day. This opportunity is only for half a day, but you are not free to go to work in this half day, if you go first, you have to ask for leave, but you will have to deduct 200 yuan for leave. This money is your opportunity cost.

As the saying goes, "the wool comes out of the sheep", there is no free lunch in the world, which has been recognized by this society and proven by time. ‍‍

There is no pie in the sky, this saying is a cliché.

In terms of moral motivation, there is a free lunch in the world, for example, you buy a lunch for a beggar for him, and this meal is free for the beggar, but for you you spend money, but at the same time you say to yourself that I have done a good deed, and your own inner morality is satisfied. In this way, you can decide whether there is a free lunch or not, say yes if you are small, and say no if you are big.

There is no such thing as a free lunch: there is no such thing as a no-charge lunch in the world. The metaphor is that you have to work for everything, and don't think about getting something for nothing. The synonym is: there is no pie in the sky.

Story allusion: Once upon a time, there was a king who loved his people like a son, and under his wise leadership, the people had enough food and clothing, and lived and worked in peace and contentment. The far-sighted king was worried about whether the people would be able to live happily ever after his death, so he recruited the best people in the country. Command them to find an eternal law that will ensure the happiness of the people's lives.

Three months later, the group of scholars presented three six-inch thick silk books to the king, saying:"Your Majesty, the knowledge of the world is gathered in these three books. As long as the people read it, they can be sure that their lives are worry-free.

The king disagreed, because he didn't think the people would spend so much time reading. So he ordered the group of scholars to continue their study, and within two months, the scholars had simplified the three books into one. The king was still not satisfied, and after another month, the scholars presented a piece of paper to the king, and the king read it with great satisfaction and said:

Very well, as long as my people truly practice this precious wisdom in the future, I believe that they will be able to live a prosperous and happy life. "After saying that, he rewarded the group of scholars heavily.

It turned out that there was only one sentence written on this piece of paper: there is no free lunch in the world.

This quote comes from the pen of political scientist Duran. In an article published in 1971, he proposed two principles, one of which was that "there is no free lunch principle in the world"; The second is that "there is no such thing as an infallible principle of influence."
