Episode Description from the Publisher

What if the exhaustion you're wearing as a badge of honour is actually the thing holding you back?In this episode, I sit down with Shelley-Ann Pieterse, executive alignment coach, founder of Glimmer Coaching and former Managing Director at Accenture, to talk about one of the most important and least discussed distinctions in leadership — the difference between high performance and high functioning burnout. Because from the outside, they look identical.Shelley spent over two decades at the top of one of the world's largest consulting firms before walking away to build something more sustainable. She brings the kind of hard-won, deeply personal perspective that only comes from having lived it. We get into the patterns she sees most in high-performing women, why ambition and wellbeing are not opposites, and what it actually looks like to lead with alignment rather than endurance.This one will make you question whether you are truly performing or simply enduring.Key TopicsThe difference between high performance and high functioning burnout — and why they're so easy to confuseWhy exhaustion is not evidence of value and endurance is not the same as resilienceThe patterns Shelley sees most in high performing women — perfectionism, hyper-independence and tying worth to achievementWhat alignment actually looks and feel like in practice for a leaderA practical red, amber, green energy audit tool you can use this weekHow to set realistic boundaries without losing your reputation for reliabilityWhy most people don't need a career change — they need a different relationship with themselvesAbout Shelley-AnnShelley-Ann Pieterse is an executive alignment coach and founder of Glimmer Coaching.
