@Kathryn.McKenzie @TheSecretMarathon: What’s a defining moment in your life? Sharing my TEDxYYC talk about the Power of Positive News was a defining moment. I chose to share about my journey with mental health and how it has motivated me to share more stories of hope. The response to this talk has been amazing – it was nerve wracking to share so vulnerably at the time but I have seen such a huge ripple effect.
