I seem to have a one-track mind. When I was having babies, I did nothing else. When I do pictures, I go all out. I really think it is easier to manage my seven. You can't afford to humor each one of them. They have to learn to do things when they are told.

In this quote, Maureen O'Sullivan reflects on her ability to focus intensely on whatever task she is pursuing, describing herself as having a one-track mind. She explains that during significant life events, like having children, she devoted herself entirely to those responsibilities, and similarly, when working on pictures (films), she goes all out, immersing herself completely in her work. O'Sullivan's comment underscores her dedication and single-mindedness when it comes to important commitments, prioritizing them without distractions.

O'Sullivan also shares her experience of raising a large family, with seven children, and emphasizes the importance of discipline in managing such a household. She asserts that children must learn to follow instructions and do what is expected of them without being overly indulged. By saying, "You can't afford to humor each one of them," O'Sullivan advocates for a structured and respectful approach to parenting, where children are taught responsibility and obedience.

The origin of this quote likely stems from O'Sullivan's personal experience as both a mother and a professional actress. Having worked during a time when balancing family life and a career in Hollywood was particularly demanding, she likely had to develop a strong sense of focus and prioritization to manage both aspects of her life effectively. Her approach reflects the reality of raising a large family while pursuing a successful career.

Ultimately, O'Sullivan's quote emphasizes the importance of commitment, discipline, and balance in both personal and professional life. It suggests that success in multiple areas, whether it’s family or career, requires a focused, structured approach and the ability to stay fully dedicated to the task at hand.
