In this episode of the Sustainably Healthy Podcast, I’m diving into something I’ve been actively working on in my own life: speaking it into existence and the power of positive self-talk.

For years, I’ve struggled with negative self-worth, comparison, and that constant “I’m not enough” soundtrack playing in the background. And honestly? I used to think affirmations were super cringy. 🙃 But lately I’ve been learning more about the science behind how we talk to ourselves — things like neural pathways and your Reticular Activating System (RAS) — and how your brain will always go looking for evidence of whatever you tell it is true.

In this episode, we chat about:

• Why your brain believes everything you tell it (good and bad)

• How negative self-talk keeps you stuck in all-or-nothing mode

• What I’ve been learning from neuroscience content and how I’m applying it

• Real-life examples from lifting, my fertility journey, and money mindset

• How to start shifting “I can’t” into something you actually can believe

• Using neutral self-talk on the days when “rah-rah positive” feels impossible

You’ll walk away with practical ways to start talking to yourself like someone you actually care about — and how that shift in identity can change the way you show up for your health, your habits, and your life. 💛

At the end, I also share what’s new inside The Challenge That Lasts (TCTL), our updated app, pricing changes for 2026, and how you can still lock in the founding member rate.
