If you could brew a hot cup of happiness, what ingredients would matter most?
Back when my sweet tooth was tipping over the edge, my first answer would’ve been three tablespoons of sugar. Now it’s the occasional half-teaspoon of honey.
Alright—back to the point.
Growing up, I was told (or maybe sold) the idea that happiness is a matter of success: more money, more achievement, more recognition. But one of the longest-running research projects on happiness tells a quieter truth.
Ever heard of the Harvard Study of Adult Development? I hadn’t—until I heard it mentioned on a podcast.
I had hit that familiar wall of writer’s block, hoping it would magically crack. It didn’t. But stepping outside for some fresh air and listening to an engaging conversation in my headphones? That helped.
That day, I was tuned into The Diary of a CEO, featuring Dr. Robert Waldinger, who leads what is often described as the world’s longest-running study on human happiness. While it surprised me, it also made perfect sense.
What the Harvard Happiness Study Found About Relationships
The study began in 1938 and has followed lives over decades, asking a simple question: What helps people stay healthy and happy over time? The answer keeps coming back to the same conclusion: Not fame. Not wealth. Not IQ. Instead, the research illuminates the importance of relationships, suggesting that the quality of our connections with friends, family, and even coworkers plays a crucial role in our long-term health and happiness.
Strong bonds give us a place to land. They lower stress, soften hard seasons, and help us stay steady when life gets sharp. The study’s message isn’t complicated—just easy to forget: the people we keep close shape how well we live.
“Good relationships keep us happier, healthier, and help us live longer.” – Dr. Robert Waldinger
Which raises the question at the heart of the book I’m wrapping up now:
What happens when the very thing we need most—connection—is turned against us?
There have been moments in my life when my beliefs were questioned, my instincts felt blurry, and the ground under me started to shake. Most of us are wired for belonging. We want to feel chosen, understood, safe. When that longing is met with warmth, it can heal us.
But when it’s exploited, it can quietly unmake us.
And it’s more common than we like to admit. At some point, many of us stumble into an unfortunate connection—someone who doesn’t build bonds, but uses them. Sometimes the harm is subtle and confusing. Sometimes it’s devastating. And often it isn’t loud. It’s slow. It starts with charm… then small tests… then isolation disguised as “love,” “truth,” or “help.”
While researching for my novel Justine—a story rooted in revenge horror and suspense—I fell down a few research rabbit holes—cult documentaries, books, survivor stories—and one thing kept echoing: the trap often begins with warmth.
Healthy connection makes you more yourself.
Manipulation makes you less yourself.
The comforting part of the Harvard study isn’t only what it proves—it’s what it suggests: you can build a better life by building better bonds. And you don’t have to do it perfectly. You just have to start noticing what’s healthy for you.
If you want a small check-in for the week, try this:
Who helps you feel more like yourself—and who makes you feel less like yourself?
Even noticing the difference is progress.
