Need, I dunno Champ. Maybe if at 20 you’d been exposed to all different kinds of thinkers- Adam Smith, Kant, Locke, Nietzsche, and so on, you might at that tender age be wise beyond your years. We don’t all go at the same speed. Maybe the better message is “if you’re not still challenging your views at 50, it’s time to admit defeat”?
For the record, I typed “Jeez” and spell check decided I meant “Need”. I should just turn that shit off.
