Chronically late: why you always leave 10 minutes behind

You woke up with an hour to spare. Had coffee, got dressed, even made the bed. Then, with ten minutes left, you decided to answer one message. When you checked the clock again, your leave-time had passed eight minutes ago. Again.

The ten minutes that evaporate

Chronic lateness rarely comes from not caring. It comes from two sums the ADHD brain gets wrong in sequence. First, time blindness: "one quick reply" feels like two minutes and eats twelve. Second, route optimism: you estimate the trip using the best-case day in history, the one with no traffic and parking at the door.

There's a third, sneakier factor: leaving the house is a transition, and transitions are expensive. Dropping what you're doing to grab keys, coat and shoes costs the same effort as dropping any task midway. Your brain postpones walking out the door for the same reason it postpones starting a report.

The bill nobody hands you directly

The person waiting can't see the machinery. They see the pattern: you arrive 10 minutes late, every time. A coworker concludes the meeting doesn't matter to you. A friend concludes they don't matter. And you, who left home running and sweating, spend the rest of the day in guilt over something you swore wouldn't happen today.

What works in practice

• Time your real exit. Spend a week measuring the gap between "I'm leaving" and the door actually closing. The number tends to shock, and it's the one that belongs in your math, not the imaginary 5 minutes.
• A leave alarm, with a name. One alarm saying "leave NOW for the dentist", plus one 15 minutes earlier announcing that the transition window has opened.
• Ban the final "quick task". The last 10 minutes before leaving are a dead zone: no messages, no dishes, no fast email. Wait by the door, bored, on purpose.
• Stage your exit the night before. Keys, bag and wallet in the same spot, always. Every item you hunt for on the way out charges 3 minutes and a shot of panic.

Where Nuky comes in

Lateness gets decided before the clock does: at the moment someone needs to tell you the leaving window has arrived. Nuky plays that role: you schedule the commitment and the reminder comes and gets you with real lead time, at transition time, instead of at the time you were supposed to already be there.
