Here’s a tiny list of things that take longer than we imagine they do:
– Buying three items or fewer from the supermarket
– Eating at a restaurant
– Taking a flight
– Writing a program
– Almost every large infrastructure project
– Installing plumbing
– Cooking a meal
– A drive across the city (going by Google Map’s estimates)
– A visit to the doctor
– Household contract work
– Fixing a bicycle
– Checking email
– Going to bed
If you don’t believe me, try measuring with a stopwatch.
The problem isn’t that we do not have enough time. It is just that the more time we have on our hands, the more optimistic our estimates seem to get.
