How many times have you used salt and pepper shakers?
They work perfectly practically every time. You don't have to worry about whether salt or pepper is going to come out. You shake it and it does.
When I was 10 we went on a school camp. Everyone was around the table able to eat the camp food. Then my friend Kaushal grabbed the salt shaker to use on his meal.
The lid wasn't on properly and the salt went all over his meal. Too much.
15 years later and I can still remember his face when he tipped a full salt shaker onto his plate.
I used salt and pepper shakers today and I can barely remember it.
We take perfect processes for granted. All the things that happen without us noticing.
And people often strive to make their work perfect. But they forget, it's the less perfect stories that are remembered most.
