It's official: 2009 was a more stressful year than 2008. But if you think being wealthy will make you happier, you might be disappointed.

According to the Gallup-Healthways Well-Being Index, Americans suffered more stress last year, with fewer happy, stress-free days. The daily polls that help calculate the index found that many of the most stressful days came early in the year, when the country was facing extreme economic turmoil. The days surrounding the House's passage of the stimulus bill clocked in with some of the highest readings of the year.

More money, more problems?
Obviously, financial stress is a big contributing factor to our unhappiness. Interestingly, though, after a certain point of financial stability, more wealth does not necessarily make us more happy.

A 2006 study by Nobel Prize winner Daniel Kahneman and colleagues found that people with above-average income are barely happier than others in moment-to-moment experiences; they actually tend to be more tense. Focusing on the illusion that wealth makes you happy may in fact have the reverse effect. 

Give a little, get a lot
So if money and status don't contribute to happiness, then what can you do to be happier? According to a recent article in the New York Times, donating gifts -- of money or time -- can not only lift spirits, but actually improve one's physical health. The article followed the story of a young woman with multiple sclerosis who gave a gift a day for 29 days, and experienced a noticeable improvement in her health. The idea is to "step outside of your own story long enough to make a connection with someone else."

Along those lines, we'd like to extend a sincere thank you -- and congratulations! -- to the Fool community for supporting our 13th annual Foolanthropy campaign. Foolanthropy is the Motley Fool's philanthropic effort focused on financial literacy and volunteerism. This year, the Fool "adopted" a local D.C. charter school by pledging $0.10 for every community comment, discussion board post, and blog post throughout the campaign. What happened next was truly impressive: The community engaged in a grassroots effort to boost our donation to the school, which ended up totaling $11,596.30. Here are some highlights:

  • Community participation in blog posts like this one helped raise the total exponentially.
  • Spontaneous "matching" contributions added $3,000 in direct donations to the school.
  • Fool co-founders Tom and David Gardner were inspired to make generous personal donations.

In addition to our monetary contribution, Fool employees will volunteer throughout the year, imparting our financial wisdom on students and parents, in hopes of helping them achieve the financial stability that can make a difference in their overall happiness.

A Foolish pat on the back
While several well-known corporations such as Bank of America (NYSE:BAC), Charles Schwab (NASDAQ:SCHW), JPMorgan Chase (NYSE:JPM), Allstate (NYSE:ALL), McGraw-Hill (NYSE:MHP), and Ford (NYSE:F) have philanthropic efforts focused on financial literacy, few have such a passionate and dedicated community as The Motley Fool's. Since Foolanthropy began, we have collectively raised $3 million. 

As Fool writer Dayana Yochim put it: "Maybe a handful of Fools teaching money lessons in one D.C. public charter school can't save the next generation from the financial missteps of the previous ones. But student-by-student, we're going to do our best."

So again, we thank you for your Foolish involvement in the campaign, and encourage you to seek out volunteer opportunities in your own community. Perhaps it will bring more happiness in 2010, and increased well-being. And heck, maybe we can save the next generation from the financial missteps of the previous one!
