In the context of Stephen King's "Storm of the Century," the quote reflects the reality of life's transactions, emphasizing that the world operates on a system of exchanges where value varies greatly. Often, we find ourselves paying small prices, but just as frequently, the cost is significantly higher. This suggests a harsh truth about the sacrifices and investments we make in various aspects of life, including relationships, choices, and even survival.

The phrase "Sometimes, it's everything you have" underscores the high stakes inherent in these exchanges. It highlights moments when individuals may have to sacrifice everything they possess, whether emotionally, materially, or otherwise, to navigate life's challenges. King's narrative likely explores themes of desperation and the cost of survival, illustrating how the demand of life can strip us down to our very core.
