The morning I run late and the morning I leave early are separated by almost nothing on the clock. Five minutes. Ten, on a bad day. Yet the man who walks out late is a stranger to the one who walks out early. The clock barely moved. Everything else did. Rush, it turns out, has almost nothing to do with time. It is a state you enter — a leopard loose in a modern mind.

Your default heaviness is no character flaw. It is a survival tool that outlived the danger it was built for. You inherited a guard dog from ancestors who genuinely needed it, then moved to a neighbourhood with no thieves. The dog stayed. It still barks at the postman every single morning, faithfully, with its whole heart, certain it has saved your life again. You thank it. You have learned to call this being realistic.

A mathematician told me AI has consciousness. China built an AI empire while we argued. A robot stood in a kitchen flipping eggs, looking deeply unbothered. One word kept circling back. Approximation. The machine cleans to satisfactory and stops. So does my son. So, it turns out, does civilisation — medicine, law, engineering, all of it. The machines learned our oldest trick. What happens next is the only part they cannot approximate.

Forty years ago, my elder brother used to drag me back from the shot put circle on competition days. He was a javelin thrower. Tall, serious, allergic to shortcuts. He would block me with one hand and make me do arm circles. I hated it. I won more often when I listened to him. A cold body misses shots. A cold mind misses life. The five minutes before everything are the five minutes that decide everything.

I went to Mawlynnong in October 2018 to walk through Asia's cleanest village. I went home with something else. A decision I had been postponing for six months made itself in a single morning. Same man. Same facts. Different brain. This blog is about the prefrontal cortex, decision fatigue, and the strange truth that the smartest part of you is also the first to leave the room. Schedule your big decisions accordingly.
