RAOK (random act of kindness).
Do a small act of kindness for someone. Hold the door, pay for the person behind you in the drive thru, help someone with their groceries, stop to let someone cross the street while you’re driving, donate old clothes, walk dogs at a shelter, plant a tree, volunteer, snowblow the neighbour’s driveway, give back to those less fortunate than yourself.

You’ll feel great having done something for someone else, and create good karma in the process.
