The real sophistication here isn't permission to curse—it's the recognition that discernment itself is a skill we must *practice*, not something that arrives with age. Most people muddle through life reacting to every perceived slight, deadline, and opinion as though each carries equal weight, mistaking exhaustion for seriousness. When your teenager finally stops caring what the popular kids think but *does* care deeply about a friend's trust, that's maturity: the hard-won ability to separate the genuinely important from the merely urgent. Manson's point is that growing up means building stronger filters, not becoming callous.
