If you are a worrywart you can't be a ninja. You can't rise up and fight when the weight of the world is pressing you down. Your family needs you to be sane and not bogged down in fear.

I remember my father, who had served in Vietnam, once talking to me about how real courage is when you're scared out of your mind but you do what you have to do anyway. I didn't feel very courageous at the moment. I felt like a small mouse in the mouth of a lion.
