How hard is it to implement?
Answer those two questions and your day will be complete. You never know when smiling will make another person think that life is not so bad after all. Or perhaps they might think that they matter if you smile at them. You'd be surprised at how much a simple smile might mean to someone who's having a very bad day or who might be going through a tough time in their life.
Put a smile on your face. But don't make it false or phony. Be sincere. Think of something going well in your life and express the joy it's bringing to you. That joy just might be contagious. Have you ever felt "down" and then heard a friend's voice or seen them smile and all of a sudden the world didn't seem so ominous? That's what you can do for others every day.
You don't need to know what's going on in the other person's life just to bring a bit of joy to them. Say hi, smile and show them that you're glad they are in this world. Say "thank you", "how are you", "what's happening", etc - talk to them. Many people long for some sort of contact from others. There was a funny movie where the guy ended up being able to read other people's minds and heard their thoughts constantly. He met an office worker in the hall when what she was carrying fell on the floor. He stopped to help her pick things up. Later he realized that she was suicidal because she felt so alone. He went to her place and talked to her and completely changed her life. How special is that.
I'm not saying you can read minds but you can change people's lives with a simple smile, a simple word.
How many people can you help today?
What did your face reflect yesterday?
What do you want it to reflect?
