The quote from W. Somerset Maugham's "Of Human Bondage" conveys the futility of lamenting over past events that cannot be changed. It implies that once something has happened, like spilling milk, there is no value in dwelling on it. The focus should instead be on how to move forward rather than reliving the regret and sorrow of what cannot be undone.

This sentiment reflects a broader understanding of life’s challenges; we often encounter circumstances beyond our control. Accepting that certain things are inevitable can empower us to channel our energy into more productive pursuits instead of getting stuck in sorrow over past mistakes.
