Thank you much for that quote. I tell new writers that all the time. Divorce yourself from the characters. Let them be who they are.
When you have a "similar" experience, it's makes for more spontaneity if they react differently than you.

Another great quote in the first video was "I spend a LONG TIME (my emphasis) on the outline. The outline is the only place you can see the whole movie. Once you start writing it becomes this scene, that moment."
