When you're acting and you need to cry, you want to put yourself in a position where you're trying not to cry, because that is generally what people try and do. They try to hold on to their emotions, they don't want to lose them.
I like acting for myself as a director. I act and I know that I'll have a chance to have some say in what gets used and that I'll be able to give myself enough takes and be on the same page as myself about how the scene should play.
