One of the easiest and most powerful ways to feel happier is for us to do something nice for someone else.

It’s also a great way to make the world better: Odds are, your kindness will radiate outward. Research shows that one person’s kindness has the ability to inspire acts of kindness in others, which may in turn influence the actions of even more people.

Take Action: Smile at someone in an elevator. Tip outrageously, and give a dollar to every homeless person you pass. Offer someone else your seat on the bus, or that great parking place you could easily sneak into. Say something kind to someone who’s having a hard day.
