Some thoughts don’t resolve—they just circle back, again and again, feeding a sense of regret, anger, or helplessness. Rumination, the act of mentally looping through the same distressing ideas, can quietly take hold and reshape how the mind responds to everyday life. Left unchecked, it becomes easier to slip into negativity without warning. But the same mechanisms that deepen these patterns may also offer a way out. If repetition wires the brain for one kind of thinking, could it be trained to lean toward something more hopeful instead? The answer may depend on what you choose to revisit.
