In long experience I find that a man who trusts nobody is apt to be the kind of man nobody trusts.
It all changed when I realized I'm not the only one on the planet who's scared. Everyone else is, too. I started asking people, Are you scared, too? You bet your sweet life I am. Aha, so that's the way it is for you, too. We were all in the same boat. That's probably what is so effective at our workshops. When I ask, Who else feels like this? the whole room of hands goes up. People realize they are not the only one who feels that way.
