Brené Brown is the only person whose self-help Kool-Aid I drink. She strikes me as vastly different from self-styled how-to-live-your-life-with-purpose gurus – more wise, more authentic, more inspiring and more useful. I love her so much that even when she joined the cult of Oprah, I chose to look the other way. As long as she keeps speaking the truth about vulnerability, shame, empathy, courage and what she calls ‘wholeheartedness,’ she can worship Oprah all she wants.
