You likely thank people often each and every day. And that’s a good thing. It’s a way of showing gratitude. And studies have found that showing gratitude may have positive effects on your mood. It may help you feel happier and more upbeat. And it may help you feel less lonely. Today, when you thank someone, try to do so deliberately and mindfully. Really think about why you are grateful to that person. You may even want to share your thoughts with that person. It might just make their day—as well as yours.
