Hardiness with Dr Paul Taylor

See omnystudio.com/listener for privacy information.

Viktor Frankl wrote that the last of the human freedoms is “to choose one’s attitude in any given set of circumstances.” But when we're going through challenges, our emotions show up automatically, so what can we actually choose?
In this episode, Carly draws on Frankl’s Man’s Search for Meaning and Morita Therapy to explore what choosing our attitude looks like in practice. We can’t choose our first reaction. We can choose what we do next.
Carly is a counsellor and coach who specialises in building psychological hardiness, which is the ability to navigate challenge, stay engaged, and take meaningful action under pressure. Her work integrates modern psychology with Eastern and Stoic approaches, helping people build resilience, live with purpose, and respond to life’s challenges with greater clarity, courage and steadiness.

In this episode, Dr Paul Taylor talks with integrative practitioner Dr Christobelle Yeoh about protecting cognitive health. They start with the rise of early cognitive decline, brain fog and stress, including during menopause. Dr Yeoh's central idea is that thinking depends on the body. Cognition rests on the lower-order systems that feed the brainstem: the gut, vascular tone, blood chemistry, breathing and the cranial nerves that read signals of safety. They explain how chronic stress and the brain's constant threat prediction affect it. They also cover why top-down approaches like CBT work best alongside bottom-up, body-based ones. The second half is practical. They look at common mismatches and what to do about them: get morning sunlight and keep a circadian rhythm, eat at regular times in daylight hours and prioritise protein and whole foods, and fix the basics before relying on supplements such as DHA, creatine and ubiquinol. They also cover CO₂-tolerance breathing, and movement that challenges balance and coordination to support neuroplasticity.
Key takeaways
Brain and body are not separate. Cognition depends on the health of the body's regulation systems.
Get outside for morning light soon after waking, and top up with light through the day.
Eat in daylight hours, include protein early, favour seasonal whole foods, and cut ultra-processed food.
Sort out the basics (light, food, sleep, hydration) before relying on supplements.
Combine top-down tools like CBT and ACT with bottom-up work like breathing, movement and gut health.
Choose movement that challenges balance and coordination, such as boxing combinations, dancing or crawling.
Start gently with breathwork. CO₂ tolerance practice is a safe place to begin, and cathartic breathwork needs guidance.

Most of us spend a lot of time listening to the voice in our heads, especially when it turns negative. This week Carly looks at what happens when you start answering back instead.
She explores research by psychologist Ethan Kross showing that talking to yourself using “you” or your own name helps you perform better under stress and see challenges as less threatening. She also looks at how Marcus Aurelius used his private journal to coach himself.
In this episode:
Why we listen to our negative self-talk as if it’s the truth
How using your own name creates helpful distance
The sage and the gremlin
A simple way to coach yourself in the moment
