Smiling is one of the most natural forms of communicating how you feel. No two smiles are alike. You smile when you're happy, when something is funny, or even if you're nervous. What's great about smiling is you can connect with a total stranger and it can change the way your day continues or have a positive effect on them. With a slight grin, you can tell someone I am here with you. I SEE you.
So, next time you are on that packed train or busy street, smile at someone and see what happens...it might just change your life!
