In Victor Hugo's "Les Miserables," the character reflects on the burden of overwhelming troubles. They often find it difficult to look back at their past, as the weight of their misfortunes can cloud their perspective. The notion suggests that individuals consumed by adversity tend to focus on the present and the future, rather than dwelling on what has already occurred.

This attitude highlights a psychological response to hardship, where constant challenges prevent one from reflecting on previous experiences. It emphasizes the idea that for those caught in a cycle of troubles, looking backward can be a painful reminder of their ongoing struggles rather than a source of strength or learning.
