Perseverance is a good thing: the ability to keep going when things seems difficult or even impossible. In Chamber of Secrets, Ginny's long-time resistance to Voldemort and Harry's willingness to keep living his life at Hogwarts, even though everyone suspects him of being Heir of Slytherin, both show perseverance. But we're not just using perseverance in the proper, positive sense. There are plenty of people in the Harry Potter novels who willingly endure hardship to achieve Dark, evil goals. For example, what are Tom Riddle's months of patiently gaining control over Ginny Weasley but proof of his perseverance? How about the twelve years that the Dursleys spend trying to repress the magic right out of Harry? They keep trying, even though it's not going to work. We're often told to keep trying, keep working hard and we'll succeed. We also need to consider, though, whether the goals we're working towards are worth our perseverance.
