You might assume that someone's angry outburst would shock you, but today it will inspire you. Their passionate defense of (or argument for) what they strongly believe in is something you can learn from. What do you feel passionately about? Whether it's a certain political position, type of music, charity, or hobby, you should get more involved with it today. Join a society, pledge a donation, or do something else that helps you put your energy where your interests are.
