It's always a problem when you're working with people you don't really know. Most filmmaking is about shaking hands and just starting. You know, these month - or two-month-long endeavors that millions of dollars are based on, and the people doing them don't even know each other, or know each other under pressure, or know each other when things are really... Which filmmaking is completely done under in many circumstances. You're under constant crisis, making a movie.
If you have done good, set your mind upon it so that it may be repeated over and over again. Allow yourself to be pleased by good. Accumulating good is joyful.
