"I've been on a calendar, but I've never been on time"

Marilyn Monroe's quote is a reflection on her life and the method she lived it. She was a star, a celebrity, and her life was often on display for the public to see. She was always in the spotlight, and her life was typically documented in calendars and publications. However, regardless of her popularity and success, she was never able to stay up to date with the demands of her life. She was always running late, never ever able to stay up to date with the expectations of her fans and the public. Her quote is a suggestion that even though she was a star, she was still human and had her own struggles. It is a suggestion that no matter how effective somebody is, they still have their own battles and can't constantly keep up with the needs of life.
