It seems that we have it backward in our society. We tend to look up to people who are under a great deal of stress, who can handle loads of stress, and those who are under a great deal of pressure.
Every year of my life I grow more convinced that it is wisest and best to fix our attention on the beautiful and the good, and dwell as little as possible on the evil and the false.
I love it when characters surprise you, just like real people. When I write a scene I just try to make the characters behave in a way that feels natural to them. Sometimes that means they make a left turn and do something unexpected. Those are always the best scenes in my opinion.
