As the lottery craze continues to boom, there's no better time to revisit Harvard professor Sanjiv Chopra's wise words about money and happiness.
What makes us happy in life? It seems like a straightforward question, but it's one that we find ourselves asking every day.
There have been several possible answers as to where happiness comes from. One of the most debated concepts is that happiness comes from having more money. But Dr. Sanjiv Chopra, a professor of medicine at Harvard Medical School, disagrees.
"Winning a $20 million lottery ticket won't make you happier. Research has shown that after one year, lottery winners go back to their baseline. Some are even less happy," he said in TED talk earlier this year.
"A few probably spent their money on a big mansion or a fancy car. Maybe they spent it all on gambling. But even so, at the end of three months, it's just a house, it's just a nice car. You get used to it," says Chopra, who has written a number of books about happiness. He calls this phenomenon hedonic adaptation, which is a concept that refers to people's general tendency to return to a set level of happiness despite life's ups and downs.
In the talk, Chopra explains the four things that have been scientifically linked to happiness:
1. Friends and family
Developing a close bond with people we trust and confide in is essential to our overall well-being. "Choose your friends wisely and celebrate everything small and good with them," Chopra says.
Many others have stressed the importance of having deep and meaningful relationships. "The world is suffering from an epidemic of loneliness," former U.S. Surgeon General Vivek Murthy wrote in a 2017 Harvard Business Review article. If we cannot rebuild strong, authentic social connections, we will continue to splinter apart — in the workplace and in society."
Researchers have also warned that "loneliness and social isolation can be as damaging to health as smoking 15 cigarettes a day," whereas friendships can "reduce the risk of mortality or developing certain diseases and can speed recovery in those who fall ill."
2. Forgiveness
"The ability to forgive frees you from the burdens of hate and other unhealthy emotions that can negatively impact your happiness quotient," says Chopra.
He cites Nelson Mandela as a hero who truly mastered the art of forgiveness. In 1990, when the legendary freedom fighter emerged from his 27 years of prison, he was asked whether he had any resentment toward his captors.
"I have no bitterness, I have no resentment. Resentment is like drinking poison and then hoping it will kill your enemies," Mandela responded.
Anyone who's ever felt they've been mistreated (most likely each and every one of us) knows that the act of forgiving can be challenging. But Karen Swartz, director of the Mood Disorders Adult Consultation Clinic at The Johns Hopkins Hospital, says that "making a conscious decision to let go of negative feelings whether the person deserves it or not" can lead to more than just increased happiness.
Studies have found that it can also lower the risk of heart attack, improve cholesterol levels and reduce blood pressure, anxiety, depression and stress.
3. Giving
Chopra says that getting involved with charities and donating money to help others is one of the most fulfilling ways to spend your time and money. Researchers have even suggested that people who volunteer have more happiness, higher self-esteem and an even a lower mortality rate.
A study from the University of Chicago and Northwestern University found that giving, rather than receiving, leads to long-term happiness. In one experiment, 96 participants were given $5 every day for five days — with the option to either spend it on themselves or on others.
"Everyone started off with similar levels of self-reported happiness," the researchers wrote. "Those who spent money on themselves reported a steady decline in happiness over the five-day period. But happiness didn't seem to fade for those who gave their money to someone else."
4. Gratitude
"There's a wonderful anonymous quote that goes, 'If you don't know the language of gratitude, you'll never be on speaking terms with happiness,'" Chopra tells the audience.
Practicing gratitude can be as simple as saying "I'm grateful" at least once a day. In fact, one study from the American Psychological Association found that doing so can help people savor positive experiences, cope with stressful circumstances and strengthen relationships.
"Taking time to think about what you're grateful for makes you more aware of the positive things in your life," says Chopra. As a result, "it makes you less biased by the fewer negative things in your life."
