What Not to Say to an Actor

What are three key things that you shouldn't say or do to your actors? Whats a better way to director your actors that you took away from this video?

Direction towards actors should not be vague. Instructions such as "give me more" and " bring it up" is unhelpful to the audience. Throwing a mixture of emotions to the actor is also ineffective as well. Simply naming an emotion is already ineffective, and combining contradicting emotions can be even more confusing to the audience. Bringing up another actor's name is rude towards the actor. Talking insensitively about other actors is unappealing as well. Having a positive environment and creating that as a director is important for the audience to freely express themselves.
