Over the past year, more than ever, I have learned that smiling is truly one of the most powerful things there are. Two friends of mine are masters of smiling even through the toughest of times and it is one of the things that I admire most about them. Many times, they taught me that just a simple "hello" or "how are you?" with a genuine smile could make someone's day; It's a great thing. Smiling despite your mood has been found to actually improve your mood and in turn, make others happier. I have changed for the better by having these friends in my life and I really do mean it when I say we would all be better off if we just smiled more often.
