I reviewed the Financial Conduct Authority’s article “The golden rules of investing” (https://www.fca.org.uk/investsmart/golden-rules-investing) and extracted its plain‑language guidance—only invest when you can afford to, set realistic return expectations and understand charges, know what you are investing in and liquidity, diversify, take a long‑term view and review holdings—that directly supports Part 2: The Purposeful Investment Landscape, Chapter “Questions to Ask”; the FCA’s regulator‑backed checklist supplies authoritative preparatory questions and risk/consumer‑protection points the book uses to help readers assess readiness, evaluate risks and costs, and make informed, purposeful investment decisions.
