It's the quickest way to feeling happy: Smile!

According to Matthew Shafer, the musician who goes by the name Uncle Kracker, he and a couple of buddies got together and made a conscious decision to write a positive song. Well they certainly succeeded! Some call it a toe-tapper; I like to call it a sing-along, feel-good song. I hope you do too.

Please sing along to Smile with Uncle Kracker on Music Sunday at Experience Optimism.
