Optimism. It was a favorite theme of our parents when they told us to hold our heads high and keep our chins up. We heard it from coaches and teachers who suggested that we should look on the bright side of things. “Count your blessings,” is advice often heard from friends and counsellors. Optimism is a recurring element of books, movies and music. If we try hard enough, we can almost hear Louis Armstrong urging us to “Grab your coat, grab your hat, leave your worries on the doorstep. Just direct your feet to the sunny side of the street.”
