This one is very probably genuine, and it comes with an unusually specific paper trail: Oren Harari’s leadership study The Powell Principles (McGraw-Hill, 2003) prints the sentence as a direct Powell quotation and footnotes it to Powell’s own memoir, My American Journey, written with Joseph E. Persico (Random House, 1995), at page 446. What we could not do is open that page. Every scanned copy of the memoir we could reach is lending-restricted, so the citation remains a very good lead rather than a confirmed reading — which is why this page says “attributed” and not “verified.”
