Lesson 1: Be willing to stand back and let your team succeed on their strengths.
Lesson 2: Don't avoid your leadership responsibilities because they are difficult.
In the boardroom, the decision came down to firing Muna for being difficult or Kristine for letting Muna be an actor. Both Heidi and Angela had difficulty telling Trump which of the two they would keep on their team. Angela said she would keep Kristine. Heidi nearly got herself fired with her indecisiveness, but also said she would keep Kristine. Muna got fired, but I would have fired Kristine for her unwillingness to manage Muna.
Lesson 3: Be willing to take a stand.
