I snapped this street performer as he chased people down to startle them with his toy puppy, stopped to show off his juggling skills, and hammed it up for anyone with an iPhone. Shoppers, co-workers on lunch break, and tourists were laughing and smiling and happy to stop and watch the street performer do his thing.
A proverb in the the Old Testament says that a joyful heart is good medicine. According to WebMD.com the benefits of laughter include increasing blood flow, boosting antibodies, and even helping with sleep.
My approach is that life is too short to be too serious for too long. You need to be able to laugh at yourself and comfortable in your own skin to make others laugh with you or even at you. Do whatever you need to do get some laughs in. Hang out with friends who like to laugh and watch some episodes of Little Rascals. Do whatever it takes. Get some good medicine of your soul.
