What if the biggest barrier to high performance at work isn't talent, strategy, or even time — but the way your brain and energy actually function?
In this grounded, practical episode of Legendary Leaders, host Cathleen O'Sullivan is joined by Alex Davids, director and founding partner of Next Evolution Performance — a global coaching business that helps leaders and teams achieve more while using less effort. With over 20 years of experience across the UK, US, Canada, Australia, and New Zealand, Alex blends neuroscience and psychology to help people understand how their brain, behaviour, and energy systems really work.
Alex opens with a concept that instantly resonates: continuous partial attention — the quiet, cumulative drain of open tabs, constant notifications, and always-on expectations that depletes the cognitive energy leaders need most. She and Cathleen explore why pushing harder is so often the worst strategy for better performance, how to identify your optimal focus period, what sustainable high performers do differently with their devices, and why busyness is frequently a cover for poor systems rather than genuine productivity. Alex also shares candidly the moment she had to admit she wasn't walking her own talk — and the small, deliberate habits she rebuilt around.
This is a conversation that will slow you down in the best way — and leave you thinking differently about where your energy is going, and what becomes possible when you stop spending it on the wrong things.

Key Takeaway:
Reduce Distraction Before Anything Else: Continuous partial attention is quietly draining your cognitive energy without you noticing. Before adding another productivity tool, try removing what's pulling your focus away. Less input is often the highest-leverage move.
Match Your Hardest Work to Your Best Energy: Not all hours are equal. Identify when your energy peaks and protect that time for your heaviest thinking — doing it the other way around costs you far more than you realise.
Busy and Productive Are Not the Same Thing: If overwhelm feels constant, it's a signal something in the system isn't working. Keep asking: is this actually the best use of our energy right now?
Give Your Device a Job Description: Sustainable high performers have a defined relationship with their phone — not just a phone. Deciding what it's for, and what it isn't, is one of the simplest boundaries you can set for your focus and energy.
Stillness Is a Performance Strategy: The brain needs space to think creatively, shift perspective, and connect ideas. Building small moments of stillness into your day isn't a luxury — it's how you stay capable of the thinking that actually matters.
