What's quietly radical here is Aristotle's insistence that excellence requires *three* separate things working together—intention alone won't do it, nor will mere effort, nor even cleverness without direction. A surgeon might intend brilliance and work tirelessly, but without the intelligent study of anatomy, she'll harm rather than heal. The quote cuts against both the "follow your passion" crowd (who assume intention is enough) and the grinders who believe sweat alone matters. It's a rebuke to magical thinking, really: excellence is boringly, reliably composed of deliberate choices repeated until they become invisible.
