Jo Blackwell is a writer, podcaster, researcher, and personal brand builder whose work centers on helping women over 50 rethink aging. After raising four children, navigating perimenopause, and spending 14 years as a professional portrait and brand photographer, Jo founded the Midlife Movement in 2018 to share the latest science on aging — challenging the outdated cultural narratives that tell women their best years are behind them. Her books include Oh Crap, I'm 50, 50 Facing 50 (a BBC-featured photography project), and her most recent release Aging Wonderfully Well. She hosts the Midlife and Beyond podcast and publishes regularly on YouTube and Substack.


In this episode:

  • How perimenopause and depression led Jo to start writing again — and how a blog became a book and a movement
  • Why building a personal brand before publishing made a measurable difference in book sales
  • The "grandmotherly vibe" lesson: why leaning into who you actually are is the most powerful branding strategy
  • How Jo uses YouTube and Substack as a content loop — and why she stopped trying to make Facebook work
  • Using audience comments, YouTube polls, and Facebook group data to decide what books to write next
  • How to overcome the fear of putting yourself out there, especially as an older woman
  • Practical advice for starting a personal brand after 50: platform selection, content planning, and setting your own boundaries
  • The right way to use AI in your writing process — as an editor and sounding board, not a content generator
  • What's inside Aging Wonderfully Well: self-ageism, perimenopause, brain research, and the science of becoming
  • Why Jo says she's never been happier than in her 60s — and what that means for women who think it's too late to start
