Anger is a waste of time, but passion is life! It means we care enough to have an opinion, a passionate opinion. Sometimes passion isn't important: should we eat at Outback or Olive Garden? Either will produce the same end result. But there are things that matter a lot, like having a doctor misdiagnose your illness as bronchitis when you have pneumonia, which is why I have a passionate distrust of doctors.
You can’t fake passion. Passion is involuntary. It causes the heart to race and the palms to sweat to talk about your passion. It dominates your being for the moment. It means something matters so much that it excites you! Passion is the heart revealed.
