Gallup found **people with a best friend at work are 7x as engaged.**

🧭 Belonging isn't a perk you announce on a poster. It may be the most underrated leadership skill there is — and the longest study of human happiness ever run makes the case better than I can. 🔬 Since 1938, Harvard has followed the same people for more than 85 years — from their 20s into their 90s — measuring everything: income, IQ, cholesterol, even genes. One thing predicted who aged happily and healthily better than anything else: the strength of their relationships. Close connection beat money, fame, IQ, and genes as a predictor of a long, good life. ❤️ How satisfied people were with their relationships at 50 predicted their physical health at 80 **better than their cholesterol did.** The study's director, Robert Waldinger, put it bluntly: *"Loneliness kills. It's as powerful as smoking or alcoholism."* And that wiring doesn't clock out when we log in: ➡️ Gallup found **people with a best friend at work are 7x as engaged.** ➡️ Yet Gallup's 2026 report shows **global engagement fell to just 20% in 2025 — an estimated $10 trillion drain on the world economy.** 💡 So belonging isn't soft, and it isn't a perk. It's human wiring — and it quietly decides whether people give a team their best or slowly check out. 🎓 I studied business strategy at Harvard and did an MBA in marketing — but no framework taught me what that 85-year study did: relationships aren't the reward for a good life or a strong team. They're the foundation. 💬 Fellow leaders: what's one small thing you do to make people feel they belong — not just perform? 👇 — Fernando Bello · Author of "Find the Best — A Full Guide for Product Management" · LinkedIn Top Product Management Voice #Leadership #ProductLeadership #ProductManagement #AI #Management #Productivity #GrowthMindset 📚 Sources for the stats: ➡️ Harvard Gazette — Harvard Study of Adult Development (relationships vs. cholesterol; Waldinger on loneliness): https://news.harvard.edu/gazette/story/2017/04/over-nearly-80-years-harvard-study-has-been-showing-how-to-live-a-healthy-and-happy-life/ ➡️ Gallup — "Why Having a Best Friend at Work Is Important" (7x as engaged): https://www.gallup.com/cliftonstrengths/en/406298/why-having-best-friend-work-important.aspx ➡️ Gallup — State of the Global Workplace 2026 (engagement 20%, $10T): https://www.gallup.com/workplace/349484/state-of-the-global-workplace.aspx
