In Victor Hugo's "Les Misérables", the quote reflects on the brevity of life and the inherent unpredictability of existence. The character acknowledges that despite the limits of time, it is essential to recognize that what seems unattainable or impossible can often become a reality. This perspective encourages a deeper understanding of life's uncertainties and challenges.

The emphasis on the unexpected suggests that preparation for unforeseen events is crucial. It highlights the idea that life is filled with surprises, both good and bad, and that our hopes and plans can change in an instant. Embracing this unpredictability allows individuals to navigate through their struggles with greater resilience and awareness.
