Running late makes every red light personal. Leave earlier and the city stops being against you.

Lateness changes how the world looks. The same lights and queues and slow walkers you barely registered yesterday turn into obstacles aimed at you, because you have no slack left and every delay now costs something real. The city did not change. The margin did.

Add ten minutes to one trip you make regularly this week and watch what happens to your mood on the way. Treat departure time as the actual decision rather than arrival time. A good deal of what feels like a stressful day is a timing problem wearing a disguise.
