Hospice doctor: the happiest people share one thing, not wealth

Dr. Jordan Grumet has sat with the dying from every tax bracket. Rich, poor, and everything between. And after years of bearing witness to how people actually feel when time runs out, he's noticed something that doesn't fit the script we're sold about money and happiness.

"Money doesn't seem to correlate. It really doesn't," Grumet tells CNBC Make It. "I've seen really, really happy poor people, and I've seen really, really miserable rich people."

What he has noticed—consistently—is regret. The people who feel genuinely fulfilled aren't the ones with the biggest bank accounts. They're the ones who didn't waste their lives becoming someone else.

The Regret Pattern

Grumet, author of "The Purpose Code," has identified what separates a life that feels complete from one that doesn't. "The happiest people I see are the ones who don't have regrets, and the ones who don't have regrets put the energy, courage, and time into becoming who they wanted to be, whether they spent money on it or not."

That distinction matters. Because money can matter—just not in the way most people think. The difference is intention. Spending $5,000 on a luxury watch that sits in a drawer produces a different outcome than spending $2,000 on a writing coach who helps you actually finish that novel you've been thinking about for five years. One is consumption. The other is becoming.

"When you direct resources toward becoming a fuller, more intentional version of yourself, you're not just chasing pleasure—you're investing in growth," Grumet writes in Psychology Today.

This might look like taking a trip to test your adventurous side. Enrolling in a class for a skill you've always wanted. Saying yes to the thing that scares you a little because it calls to who you want to become. The money is just the enabler. The real currency is the choice to invest in yourself instead of just in stuff.

Why This Matters

Here's where it gets interesting: when you spend on growth and passion, you naturally attract people doing the same thing. A writing class connects you with other writers. A hiking trip connects you with other adventurers. And it turns out—after 80 years of research, the Harvard Adult Development Study found—that these connections are what actually sustain us.

"Good relationships keep us happier, healthier, and help us live longer," says Robert Waldinger, author of "The Good Life."

The greatest regret Grumet hears from people near the end? Not "I wish I'd bought more things." It's "I wish I'd lived a life true to myself, not the life others expected of me."

Money can either lock you into someone else's script or give you the freedom to write your own. The difference isn't the amount in your account. It's where you decide to spend it.

Grumet's conclusion is quiet but worth sitting with: "The most enduring form of spending is on becoming—on growth, purpose, and passions that make you a better version of yourself."
