We’ve often heard that acts of kindness make us happier, but there’s a problem with that blanket statement: While these little kind actions make us happier at first, just doing the same act of kindness again and again won’t make us happy in the long run. Science shows that if we come to do the same good deeds repeatedly, they make less and less of an impact on our happiness—mainly because we acclimate to that behavior and subsequent reactions. So to get people out of their “acts of kindness comfort zones,” Soul Pancake got four volunteers to go above and beyond by approaching strangers, making phone calls to loved ones, and more. The verdict? Perform your acts of kindness, but constantly push yourself to do something uniquely kind, all the time!
