Renee Murphy never planned on becoming a scientist. But after years of building a career in fashion and marketing, something shifted. She made the leap into environmental science, research, and a whole new version of herself. In this episode, Renee joins us for a candid conversation about what reinvention really looks like. Not just the career change, but the identity shift, the doubt, the rebuilding. She opens up about the moment she realized she was no longer connected to the work she once loved, how she handled going back to school later in life, and what it’s meant to find a deeper purpose on the other side. We also talk about the realities of being a woman in male-dominated spaces, the power of saying "I don’t know," and why it’s okay if your life no longer fits the version you once worked so hard to build. 🎧 Listen in for a refreshing and grounded conversation on personal growth, career pivots, and the courage it takes to start over. Especially when it would have been easier not to. 00:00 – Meet Renee Murphy and her path from fashion to science 06:42 – What led her to walk away from a stable career 12:10 – Going back to school in her 30s and starting from scratch 19:03 – The mental hurdles of reinvention and doing hard things later in life 24:47 – Making peace with uncertainty and feeling behind 32:15 – How identity, ego, and purpose shift through reinvention 41:02 – The unexpected joy of finally doing something that feels right 💡 Who Should Listen?
