In "Sabotage," Arturo Pérez-Reverte explores the theme of personal agency and the influence of one's choices on life's outcomes. The quote "Each is his own luck" suggests that individuals are responsible for creating their own fortunes through their actions and decisions. This perspective emphasizes self-determination and the idea that luck is not merely a matter of chance but rather the result of one's efforts and strategies.

The narrative delves into the intricacies of human behavior and relationships, portraying how characters navigate challenging situations. Through their experiences, Pérez-Reverte illustrates that while external circumstances can be unpredictable, it is ultimately up to each person to shape their destiny by making wise choices in difficult times.
