One cold, January morning, a young man in a baseball cap walked to a local subway station in Washington. He pulled out his violin, and, over the next 45 minutes he played his heart out, playing five of the most complex pieces of music ever written. Over a thousand people walked past. It was morning rush hour.

But no one took much notice. A few people stopped and threw a couple of dollars into his open violin case. One child yanked on his mommy’s hand and told her he wanted to stay to listen to the “cool music,” but they ended up staying only a few minutes. He counted the money he made - a total of $32.17. How ironic, given that the young man was none other than Joshua Bell, a Grammy award winner and one of the world’s most accomplished musicians.
