The following is a personality profile of Tina Fey based on her work.
Tina Fey is social and boisterous.
She is empathetic, she feels what others feel and is compassionate towards them. She is assertive as well: she tends to speak up and take charge of situations, and she is comfortable leading groups. But, Tina Fey is also intermittent: she has a hard time sticking with difficult tasks for a long period of time.
More than most people, her choices are driven by a desire for self-expression.
Doesn't find either taking pleasure in life or helping others to be particularly motivating for him. She prefers activities with a purpose greater than just personal enjoyment. And she thinks people can handle their own business without interference.
