It suggests that no matter how meticulous or thorough one may be in organizing their future, unforeseen events can completely alter one's path. This reflects the idea that life's unexpected challenges or changes can render detailed plans ineffective.

Diana Gabaldon, in her book "Written in My Own Heart's Blood," highlights the need for flexibility and adaptability.
