"If I don't like seeing myself on the screen, I think when I start seeing that, that's when I think I'll stop"

In this quote, Charlize Theron is expressing her thoughts on her own acting career. She states that if she ever reaches a point where she doesn't delight in seeing herself on screen, that is when she will understand it's time to stop acting. This could be analyzed as Theron valuing her own personal satisfaction and pleasure over external recognition or success. It likewise shows her self-awareness and understanding of her own limitations and borders. Theron's words recommend that she wants to continue acting as long as it brings her delight and fulfillment, instead of for the sake of fame or recognition.
