"Tell yourself a better lie."
The first time I read that from Marisa Peer, I had to sit with it.
Because most of us are already running a story. And it didn't start with something dramatic - it started with a throwaway comment in a classroom. A look. A moment that got filed away long before you had the language to question it.
"You're too sensitive."
"You're not the academic one."
"People like us don't do things like that."
And quietly, over time, the mind stopped asking whether those things were true. It just absorbed them - and started building a life around them.
What's compelling is how clearly the science now supports what sits at the heart of this work. Research by Stanford psychologist Dr. Alia Crum shows that mindset has measurable effects on our biology, our behaviour, and our outcomes. Not metaphorically. Literally.
The words you repeat to yourself are not neutral. They are instructions.
This is the work I do at Belief by Design - not positive thinking layered over old wounds, but going back to where those beliefs were first formed, and choosing something different.
You didn't choose the original story. But you can choose what comes next.
What's a belief you've outgrown - but still catch yourself living by?
