Do you ever get upset when you cut a character or throw out pages, or even chapters?

I used to get very upset when I would “waste” a day or a week going off on a plot tangent or approaching a scene from the wrong point. Nowadays, I just mutter a little and get back to work.

I think I have to test out my characters, sometimes following them down the wrong path, to get to know them better and to understand the world of the story.
