Here’s the quiet pattern I see in senior leaders under sustained pressure…decision quality drops long before motivation does. Not because people don’t care, but because their nervous system is overloaded. 🧠Our brains have a limited capacity for self-regulation and decision-making across the day. ❌Prolonged cognitive demand increases mental fatigue, reducing accuracy, impulse control, and judgement ❌This effect is linked to changes in prefrontal cortex activity and rising str

Most leaders I work with assume that if the science is strong enough, the outcomes should follow. Powerful intervention in… better results out. But the evidence suggests it’s not that simple. A large real-world study published in JMIR  followed over 126,000 adults with obesity  who were prescribed tirzepatide and enrolled in a digital weight-loss service ( J Med Internet Res, 2026 ). What the researchers explored wasn’t a new drug mechanism… but something far more human: enga

Most leadership and health work happens once people are already exhausted, reactive, or burnt out. That work matters deeply. But there’s something profoundly different about getting in early . Early career professionals don’t need rescuing. They need foundations . The science Behaviour science is very clear on this. Habits formed earlier in adulthood are more likely to persist because they become identity-linked, not task-based. Research on habit formation shows that repeated

We often assume that better decisions come from more effort…More hours…More thinking…More grit. In reality, sustained decision quality depends far more on recovery  than effort. Here’s the reframe 👇 Your brain is a biological system, not a spreadsheet…and like any system, it degrades under continuous load. 🪫 The science is very clear. 🧪 What the research shows Decision-making draws heavily on the prefrontal cortex. This region is highly sensitive to fatigue, stress and sle
