In the book "Spy of the First Person" by Sam Shepard, the author reflects on the uncertainty of the future. He suggests that while we may anticipate events to unfold in our lives, we remain unaware of how various elements will eventually coalesce. This unpredictability is a fundamental aspect of experience, leading to a sense of anticipation and anxiety about what lies ahead.

Shepard's quote emphasizes the idea that although something will inevitably occur later, the specifics remain unknown. This notion captures the essence of life's unpredictability, highlighting how we often navigate through various possibilities without a clear vision of the outcome. It speaks to the human experience of waiting and contemplating the mysteries that time holds.
