Do try this experiment at home.

 

Thank you note

Each morning, set aside two minutes to send a quick email, tweet, direct message or text to express gratitude to one person you know. “It’s so simple,” positive psychology expert Shawn Achor says of the technique. Social connection is a predictor of long-term happiness, he explains. Studies show that senders feel happier with every dispatch. Phone calls work, too, of course. “Even better is face to face.” Take two minutes. Try it now. Brighten someone’s day.
