“HOW TO BUY HAPPINESS”
Recently I started listening to TED talks in order to enhance my English skills.
Today I would like to share about an interesting topic from it.

I have a question; do you think money can buy happiness?

A professor at Harvard Business School studied “HOW TO BUY HAPPINESS”.
His conclusion was, you can buy happiness when you don't spend the money on yourself.

The professor made reference to an interesting article on CNN on what happens to people when they win the lottery. One, they spend all the money and go into debt; and two, all of their friends and everyone they've ever met find them and beg them for money. It ruins their social relationships, so they have more debt and worse friendships than they had before they won the lottery.

The professor thought maybe the reason money doesn't make us happy is that we're spending it only on ourselves. So, the professor gave money to some people and made them spend it on themselves, and others were given money to use for other people and measured their happiness and saw if they got happier.

First, they carried out the experiment on a University student in Canada.
The team gave each student an envelope. Some of the envelopes was labeled "By 5pm today, spend this money on yourself." Other people got a slip of paper that said, "By 5pm today, spend this money on somebody else. Some people got five dollars; others got 20 dollars.

Some students spent it on for themselves like earrings and makeup. One woman said she bought a stuffed animal for her niece. Some students gave money to homeless people.
Some students bought coffee for themselves, but others bought coffee for other people.

At the end of the day, people who spent money on others got happier; people who spent it on themselves had no impact on their happiness. The other thing we observe is the amount of money doesn't matter much. People thought 20 dollars would be better than five. In fact, it doesn't matter how much money you spent. What really matters is that you spent it on somebody else rather than on yourself.

The professor wanted to see if this holds truth everywhere in the world or just among wealthy countries. So, they went to Uganda in Africa and ran a very similar experiment. The results were quite the same.

They decided to do a very similar thing with a sales team in Belgium. They work in a pharmaceutical company and their job is to sell medicine to doctors. The professor gave them some money. "Spend it however you want on yourself. To other teams they say, "Here's 15 euros. Spend it on one of your teammates. Buy them something as a gift and give it to them. As a result, the teams that are pro-social sell more stuff than the teams that only got money for themselves. Their sales performance was better than the others.
The professor also did the same experiment in dodge ball teams in the US. They gave people in some of the team’s money to spend on themselves. Whereas, other teams, were given money to spend on their dodge ball teammates. The teams that spend money on themselves have the same winning percentages as before. The teams that they gave money to spend on each other were the ones who won the league match!

Therefore, the professor concluded that spending on other people has a bigger return for rather than spending on oneself. If we think money can't buy happiness, we're not spending it right. People get money and it makes them anti-social. The implication is that we should stop thinking about which product to buy for ourselves, and try giving some of it to other people instead. (End)

“HOW TO Buy HAPPINESS”
I recently began listening to TED talks to improve my English skills.
Today I'd like to discuss an interesting topic from it.

I'd like to ask you a question: do you believe money will buy happiness?

A Harvard Business School professor investigated "HOW TO BUY HAPPINESS."
His conclusion was that you would buy happiness by not spending money on yourself.

The professor mentioned a fascinating CNN article on what happens to people who win the lottery. One, they spend all of the money and become indebted; and two, all of their friends and everyone they've ever met track them down and beg them for money. It destroys their social relationships, resulting in more debt and poorer friendships than they had before winning the lottery.

The professor suggested that maybe the reason money does not make us happy is that we spend it exclusively on ourselves. So the professor gave money to some people and forced them to spend it on themselves, whilst others were given money to spend on others, and their satisfaction was tested to see if they were happier.

First, they performed the research on a Canadian university student.
Each student received an envelope from the team. Some of the envelopes were numbered "Spend this money on yourself by 5 p.m. today." Others were given a slip of paper that said, "By 5 p.m. today, spend this money on someone else." Some citizens received five bucks, and others received twenty dollars.

Any students used it to purchase items for themselves, such as earrings and lipstick. One lady said that she purchased a stuffed toy for her niece. Any students donated funds to the poor.
Any students purchased coffee for themselves, and others purchased coffee for others.

People who spent money on others became happy at the end of the day; people who spent money on themselves had little impact on their satisfaction. Another thing we notice is that the sum of money doesn't seem to matter much. People believed that twenty bucks would be preferable to five dollars. In reality, it makes no difference how much money you spend. What matters most is that you spent money on someone else other than yourself.

The professor needed to know if this is so all over the world or only in rich nations. Then they traveled to Uganda, Africa, and conducted a very similar experiment. The outcomes were almost the same.

They agreed to do something similar for a sales team in Belgium. They work with a pharmacy firm and supply drugs to physicians. They were given money by the professor. "Spend money on yourself however you see fit. They tell other players, "I'll give you 15 euros. Spend it on a member of your staff. Purchase a gift for them and present it to them. As a result, pro-social teams outsell teams who just got money for themselves. Their market success was superior to those of the others. The professor conducted the same experiment for dodge ball players in the United States. They gave some of the team's resources to individuals to use on themselves.Other players, on the other hand, were given cash to spend on their dodge ball buddies. Teams who expend money on themselves continue to win at the same rate as before. The teams to whom they gave money to spend on each other won the league match!

As a result, the professor concluded that spending on others yields a greater return than spending on oneself. If we believe that money cannot buy happiness, we are not investing it wisely. People become anti-social as a result of receiving rent. The implication is that we should avoid worrying about which commodity to purchase for ourselves and instead want to give more of it to others. (Summary)
