Do you say hello to each individual that you walk by during the day? I never use to. My current job focuses a lot on being friendly and that involves greeting each individual you encounter during the day. And let me tell you, it is contagious, kind of like yawning. I find myself saying hello and smiling at everyone, I mean everyone, I brush by. Not only does it make me feel good to smile and say hello, but I hope it encourages others to pay it forward. Even if I don't feel like it or my day is not a smiley/hello kind of day, I still do. My hopes that my hello leads to a million more hellos or if all it does it makes that person feel good for 1 second, it was totally worth it.
