Smile

I came across the following quote in a thrift store:

"A smile can never be kept; it can only be given away."

Everyone can smile. And you never run out of smiles, regardless of how many you give out. Smiling is the easiest form of service. And as service it will lift those to whom it is given and the giving will lift the giver. I highly recommend the practice of smiling often and to everyone. You never know whose day will be enlightened just because you decided to give away a smile.
