“The takeaway here is simple but powerful: just because you’re great at something doesn’t mean you’re good at everything. Unfortunately, this fact is routinely ignored by those who engage in—take a deep breath—ultracrepidarianism, or ‘the habit of giving opinions and advice on matters outside of one’s knowledge or competence.’” ―Steven D. Levitt
