SMILE!!!

It's free and easy. Smiling will not only make you feel good, but it will probably make someone else smile. Even if you think you have no reason to smile or you feel too sad, SMILE, it will make you feel better. I know life is hard and gives you many reasons to cry, you just have to show it you have even more reasons to smile. 

Smile, just smile, you never know who will fall in love with your smile. Maybe someone is sad and just by you smiling to them you instantly make them feel better.

Let's change the world one smile at a time :D
