A Life of Greatness

In this groundbreaking conversation, Professor of Genetics and longevity scientist, Dr. David Sinclair, A.O., Ph.D., joins Sarah Grynberg to unpack the future of human aging, the science of
longevity, and how we live today impacts how we age tomorrow.

From reversing blindness in mice to exploring treatments that could one day delay menopause and extend healthy human life, this episode will completely change the way you think about your body, your health, and your future.
But beyond the science, this is also a deeply human conversation about purpose, suffering, love, family, and what it truly means to live a great life.

Why aging may actually be reversible
The daily habits accelerating aging in your body right now
How stress, loneliness, and cortisol could impact longevity
The real science behind supplements like NMN, resveratrol, and NAD boosters
Why exercise, sleep, and relationships matter more than you think

How scientists are working to reverse female infertility and delay menopause
The surprising reason your “biological age” may be younger or older than your real age
Why suffering through disease and decline should not be considered “normal aging”

Have you ever stayed in something far longer than you should have, simply because you’d already invested so much into it?

In this episode of Sarah’s Thoughts, Sarah Grynberg shares one surprising pattern she has noticed among some of the most successful people she has ever interviewed. They know how to quit quickly. Not out of fear, laziness, or failure, but from a deep understanding that holding onto the wrong thing can quietly drain your energy, time, and potential.
Sarah explores the psychology behind why so many of us struggle to walk away, unpacking the concept of the sunk cost fallacy and the emotional weight of feeling like quitting means giving up. She reflects on the ways we stay too long in jobs, friendships, relationships, and ideas that no longer align, simply because we’ve already invested so much into them.

You’ll learn:
Why successful people are selective about where they invest their energy
How the sunk cost fallacy keeps people stuck in situations that no longer serve them
Why letting go of the wrong thing can create space for the right one

This episode is an invitation to rethink what quitting really means. Because sometimes walking away is not failure, it’s wisdom. It’s recognising when something is no longer aligned and having the courage to stop forcing what was never meant to fit. And often, the most powerful thing you can do is let go before it costs you more than it already has.

What happens when global success still leaves you questioning your happiness?

In this powerful conversation, rock star Richard Marx joins Sarah Grynberg to open up about fame, rejection, mindset, fatherhood and the emotional highs and lows of life in the spotlight.

Richard shares the devastating moment legendary producer David Foster told him he would never make it as a singer, the incredible act of kindness from Lionel Richie that changed his life forever, and the mindset shifts that helped him navigate anxiety, negativity and self-doubt.
He also reflects on his friendships with Olivia Newton-John and Michael Bolton, the hidden emotional crash after performing to thousands of people, and the bittersweet realisation that one day your children stop calling you “Daddy” and you never even notice when it happened.

In this episode, you’ll learn:

How Richard Marx handled years of rejection
The hidden emotional cost of fame and success
Why gratitude can change your mindset completely
The parenting realisation that left him emotional
What Lionel Richie did that changed his career forever
Why Richard says happiness is found in the simple moments

This is a raw, wise and surprisingly emotional conversation about success, identity, love, grief and learning how to truly enjoy the life you’ve built.

What if you’re not stuck, you’re just becoming?

In this episode of Sarah’s Thoughts, Sarah Grynberg reflects on a powerful, Rumi-inspired idea she first heard through her conversation with Serena Dyer, that from the moment we’re born, it’s as though a ladder is placed before us, and whether we realise it or not, we are always climbing.
She explores how every stage of life, the uncertain ones, the painful ones, the ones that feel like nothing is changing, are not signs of being lost, but evidence of growth.
Because what feels like standing still… is often the very thing moving you forward.

You’ll learn:
Why every stage of life serves a purpose, even the seasons that feel uncertain
How Rumi’s ladder metaphor can change the way you view growth and struggle
The comforting reminder that you are never truly stuck or falling behind

This episode is a gentle invitation to trust where you are, even if it doesn’t yet make sense. To remember that transformation often happens quietly, beneath the surface, long before we can fully see it. Because your life is not finished, your story is still unfolding, and the ladder has been there for you all along.

Are you waking up in the middle of the night and unable to fall back asleep… no matter how tired you are?

In this episode of A Life of Greatness, Sarah Grynberg sits down with renowned sleep expert and sleep psychologist Dr Michael Breus to unpack the science, psychology, and hidden habits that are quietly destroying your sleep.

From anxiety and racing thoughts to hormones, heart rate, and even your genetics, this conversation reveals why so many of us struggle to get quality rest… and what we can actually do about it.

Dr Breus shares practical, science-backed tools to help you fall asleep faster, stay asleep longer, and finally wake up feeling restored. This is not about rigid rules or unrealistic routines… it’s about understanding your body and working with it.

Because when you improve your sleep… you improve your entire life.

You’ll learn:
Why anxiety is the #1 reason you can’t sleep
The exact reason you wake up in the middle of the night
How to lower your heart rate to fall asleep faster
The truth about supplements like magnesium
Why sleep quality matters more than sleep quantity

Sleep isn’t a luxury… it’s the foundation of everything.
And when you start to understand your body… you stop fighting it, and start living better.
