Are you using red language or green language?
The words we choose have profound power to shape our collective reality and consciousness. Consciously selecting positive, life-affirming language can transform not just our individual experience, but our entire relationship with each other and our environment.Rather than merely reframing negatives, we can "upframe" our communication to create higher vibrations and more constructive ways of seeing the world, leading to stronger communities and more meaningful connections.Dr Claudia Gross is the author of the book Words Create Worlds. She works as an organisational development consultant, trainer, facilitator, and host. Her work focuses on conscious language use and transforming how we communicate to create more positive impact.This conversation will help youTransform negative or limiting language into more empowering "green" words that elevate consciousness and create positive changeRecognise how words shape our collective experience and future, moving beyond individual self-development to conscious co-creation of realityBuild stronger communities by shifting from isolation-based language ("you are not alone") to connection-based language ("we are in this together")ResourcesConnect with Claudia via LinkedInWords Create Worlds – Claudia’s bookVisit Claudia’s websiteConnect with Tatjana via LinkedInVisit The Human Greenhouse website to explore and connect
