A TED Talk.
The happiest people I know love music and many perform one way or another, often with others. My college friends play the ukelele; others I count as friends place the Irish drums, the bag pipe, banjos, guitars, the saxaphone; some sing formally, some are Karaoke greats, some just sing in the shower.
This man added the strengthening power of helping others to his love of music. Sharing the good you have strengthens you as well as those you share with. Enjoy and stay strong.
