Wilde’s line is funny because it turns mistakes into something we rename after we survive them. There is also a useful kindness inside the joke. Experience is rarely tidy while we are acquiring it. We make the wrong call, live with the result, and eventually understand something we could not have known beforehand. The goal is not to romanticize mistakes, but to let them become information instead of permanent evidence about who we are. What mistake has taught you something you could not have learned another way?
