Reasons to be Cheerful is a nonprofit, solution-focused website (titled “Tonic for tumultuous times”) that curates short, actionable stories across climate, communities, cities, food, culture and technology—examples include London solar microgrids, river clean-ups in Hungary, local-food disaster relief, Copenhagen’s ‘sponge city’ work, Rwanda’s Umuganda and music-based dementia therapy—making it a practical resource for investors to discover real-world, scalable climate, community and innovation solutions that signal mission‑aligned investment opportunities; this aligns with PART 1: The Purposeful Investor and the book’s Chapter “Call to Action: Our World & Our Future” by providing hopeful, evidence‑based examples that help envision a better future, amplify positive solutions, and inspire action (favoured by Steph).
