I always imagine a good leader is surrounded by people who call their mothers at the end of the day and tell them, 'Mom, you can't believe what I did today. Let me tell you about it.'
We all have faith in something: usually a mixture of some personal beliefs with modern science. I am not like that. Mostly I just believe in what personally has worked for me.
If two people believe in the same story, they might be thousands of miles apart and total strangers, but they still have a sense they can trust each other.
