I don't really get that nervous about whether people like it. You can't do anything about that. It's more technical. You spend two years of your life obsessing, picturing sound details, and you work so hard to make a movie a certain way, that you get there, and you're like - is it loud enough or whatever, so that this experience with everybody in this room is the fairest chance I can get. And then if you like it, cool, and if you don't, whatever.
Reflection doesn't take anything away from decisiveness, from being a person of action. In fact, it generates the inner toughness that you need to be an effective person of action - to be a leader.
