Writing for The Atlantic, Emily Esfahani Smith shares the findings of a study that identifies the differences between happiness and meaningfulness:
[T]he researchers found that a meaningful life and happy life overlap in certain ways, but are ultimately very different. Leading a happy life, the psychologists found, is associated with being a "taker" while leading a meaningful life corresponds with being a "giver." [...]
"Happy people get a lot of joy from receiving benefits from others while people leading meaningful lives get a lot of joy from giving to others," explained Kathleen Vohs, one of the authors of the study, in a recent presentation at the University of Pennsylvania. In other words, meaning transcends the self while happiness is all about giving the self what it wants. People who have high meaning in their lives are more likely to help others in need.
Meaning is not only about transcending the self, but also about transcending the present moment -- which is perhaps the most important finding of the study, according to the researchers. While happiness is an emotion felt in the here and now, it ultimately fades away, just as all emotions do; positive affect and feelings of pleasure are fleeting. The amount of time people report feeling good or bad correlates with happiness but not at all with meaning.
Meaning, on the other hand, is enduring. It connects the past to the present to the future. [P]eople who thought more about the present were happier, but people who spent more time thinking about the future or about past struggles and sufferings felt more meaning in their lives, though they were less happy.
Having negative events happen to you, the study found, decreases your happiness but increases the amount of meaning you have in life.
Victor Frankl, author of Man's Search for Meaning, gets the last word:
A man who becomes conscious of the responsibility he bears toward a human being who affectionately waits for him, or to an unfinished work, will never be able to throw away his life. He knows the "why" for his existence, and will be able to bear almost any "how."
