It’s Not a Discipline Problem—It’s What Happens Under Pressure

There’s a Harvard economist, Sendhil Mullainathan, who studied something most people wouldn’t think to question… why we make decisions that don’t line up with what we say we want. Not from a motivation angle. Not from a “try harder” angle.

But from what’s actually happening to the brain under pressure. What he found was simple, and a bit confronting… when time, money, energy or mental space feel tight, the brain doesn’t rise to the occasion. It narrows. It locks onto what’s urgent. And everything else — including long-term goals — quietly drops out of view. 

When I first came across that, it stopped me in my tracks a little. Because it explains something most women feel but can’t quite put words to… why food is easy when life is calm, and suddenly feels like a different game when the day has been long, messy, or mentally draining. 

It’s not random. It’s not a lack of discipline. It’s that moment where your brain shifts into “just get me through this” mode. And once you see that shift — not after the fact, but while it’s happening — you start to realise something important is sitting right there in that moment. 

This is where Dietless Living® and Personal Health Leadership™ actually begin. Not in the plan. Not in the perfect week. But in those small, almost invisible moments where your brain is looking for relief and you don’t even realise it yet. Most people try to fix the food.

But what if the real leverage point is earlier than that? What if the moment that decides everything… isn’t where you think it is?
