"I really have no ulterior motive in taking on certain roles. I have no larger issue that I really want to show people. I'm an actor, that's all. I just do what I do"

Sally Field is highlighting that she is a star firstly. She is not taking on functions to make a declaration or to push a program. She is just doing what she loves and what she is proficient at. She is not trying to be a representative for any specific cause or to make a statement about any particular concern. She is merely an actor, and she is content to let her work promote itself. She is not trying to be a leader or a role model, she is simply an actor who is enthusiastic about her craft. She is not attempting to make a statement or to press any sort of agenda, she is just doing what she loves and what she is good at.
