Positive feedback doesn’t just make you feel better, it makes you do better, too. In a recent study, a group of adults were taught a sequence on a keyboard. Those who got a compliment afterward performed the exercise better the next day than those who didn’t. You can’t count on a pat on the back every time you do something right, but you can remember to compliment those around you. They’ll benefit—and so will you. Psychologists agree that doing acts of kindness makes you happier. Think of it: A happier, more productive workday could be just a “good job” away!
