From Gray to Glorious: How She Rekindled Her Spark—Without Burning Everything Down

There’s a moment—maybe you’ve had it too—when you look around and realize your life is technically “fine”… and yet something vital is missing.

For Mary Guerdoux, that moment came wrapped in a blanket, clutching a steaming mug of tea, watching the sun rise over the French Riviera. A pandemic had unexpectedly cleared her schedule. Her baby was finally sleeping. And for the first time in years, she was still enough to feel the hollowness.

This was supposed to be the dream—stable job, beautiful home, healthy family. But somewhere in the relentless forward motion, her spark had dimmed. Joy was a memory. Purpose? Muffled under logistics.

What came next wasn’t a midlife crisis. It was a reckoning. A reboot. And it would lead her to help other women rediscover the vibrant, unshakeable energy hiding just beneath their burnout.

When You’re Functioning… But Faded

Mary is an engineer-turned-coach. But don’t let that hyphen fool you. Her work isn’t about soft platitudes or abstract pep talks. It’s about data. Energy. Measurable shifts. And getting women—especially midlife women—back to themselves.

“I work with women who are technically fine,” she says. “They’re functioning. Showing up. Getting things done. But the light’s gone out. And they know it.”

Mary's coaching clients come from all walks of life—corporate roles, entrepreneurship, parenting trenches—but they share one thing in common: that heavy, gray sense of meh that creeps in when life starts to feel like a loop.

Her mission? Help them light the fire again. And not in some flashy, superficial way. She helps women feel alive, energized, and themselves again—sometimes for the first time in decades.

Energy Isn’t Woo—It’s Measurable

One of the most refreshing things about Mary’s approach is that it’s grounded in both science and soul. She uses a tool called the Energy Leadership Index (ELI)—developed by iPEC—to measure where your energy is being spent, where it’s being drained, and how aligned it is with who you want to be.

Clients answer a series of questions. Out comes a report. Not just fluff—but actual numbers. Tangible insight. “We can measure your baseline,” she says. “And then measure your growth. The change is real. It’s trackable.”

That blend of structure and intuition is what sets Mary apart. She doesn’t ask clients to guess their way to a better life. She gives them a framework to see themselves clearly—and then build from there.

The Four Energies You’re Probably Ignoring

Mary’s work breaks down energy into four core types:

• Physical (How’s your sleep? Are you hydrated? Do you move your body?)

• Emotional (What are you feeling—and are you actually allowing it?)

• Mental (Is your thinking helpful? Or are you stuck in self-doubt loops?)

• Spiritual (Do you feel like your life has meaning?)

It’s often the spiritual energy—connected to purpose and fulfillment—that gets most neglected. “That’s the one people don’t even know how to check in on,” Mary says. “But it’s the key to everything else.”

What Coaching with Mary Looks Like

Forget sterile Zoom calls and homework-heavy sessions. Mary does much of her coaching while walking outside—sometimes by the sea, sometimes in the hills, always with intention.

Her clients don’t need to be in the same country. They just need a pair of earbuds and a willingness to move. “There’s something about forward motion,” she says. “Even if you’re just walking your neighborhood, your mind opens differently. Ideas land more softly.”

And for those who resist that first session, Mary gets it. “You don’t have to want to go outside. You just need to be curious about what might happen if you did.”

Spoiler: a lot happens. Creativity spikes. Clarity returns. The fog lifts.

When Your Life Turns Technicolor

One client’s friends said it best: “She’s become so colorful.” That wasn’t about a wardrobe change. It was energy. Aliveness. A return to who she was meant to be.

Mary has heard that again and again. Her clients aren’t just more productive or focused—they’re magnetic. Joyful. Awake. And often, unrecognizable to their former, grayed-out selves.

This isn’t about manifesting your dream life in five steps. It’s about reconnecting with your natural energy so you can show up for the life you already have—more fully, more vibrantly, more you.

Speaking While Salty (Literally)

Mary recently stepped onto a new stage—public speaking. And she didn’t do it the “right” way.

The day she recorded her pitch video, she’d just come back from the beach. Sand in her hair. Wind on her face. No makeup. “I hadn’t even washed,” she laughs. “But I knew if I waited to look polished, I’d talk myself out of it.”

So she hit record. Messy. Real. And powerful.

She got the gig.

And on stage, she told vulnerable stories—about burnout, motherhood, change. About being the woman with the tidy hair and the dead eyes. About coming back to life. “You could hear a pin drop,” she says. “And afterward, women came up to me sharing things they’d never told anyone before.”

Ready for Your Energy Check-In?

Mary offers a free tool on her website called the Core Energy Profiler—a short assessment that gives you a snapshot of how your energy is working for or against you. It’s a simple, no-strings-attached way to get a taste of what working with her feels like.

She’s not trying to sell you a package. She’s offering you a mirror. The kind that reflects what’s real—and what’s possible.

Your vibrant self is still in there. It’s just waiting for a little sun.
