It's amazing how a kindness can lift you out of a funk. I had been in one for the past few days, and then out of the blue, someone gave me a compliment that both surprised me and made me feel loads better. It changed my whole outlook for the day.
Do someone a big favor today. Say something nice to them. Your spouse, a friend, the lady at the coffee shop. Just one person. Pass that good feeling on! You'll find it makes you feel good, too.
