"...I've been thinking and teaching about Internal Ecology™: the idea that sustainable leadership and human fulfillment are built from the inside out. Not optimized. Not hacked...So, I want to walk through it, domain by domain, across the six areas of the Internal Ecology™ System: Fuel, Move, Sleep & Recovery, Calm & Regulate, Connection, and Growth. Because in each one, there is no fast track to anything meaningful. And yet, we keep looking for one."

'if look closely, the version of high performance that relies on pushing harder, digging deeper, constantly running faster, isn't actually sustainable. It's depleting. And eventually, something does start to give... Sustainable high performance is not built on how much you can push or how fast you can go. It's built on how well your internal system can support the push. This is where capacity comes into the picture.'
