Recently, I heard someone say, “I am not interested in polishing the last one percent. Just not.”
The last one percent doesn’t sound like much. For a design or writing project, that’s adjusting word spacing, line breaks, punctuation, and so on.
But one percent is a difference we can taste. Try a glass of skim milk, and then a glass of 1%. Or, if you prefer, 1% milk and 2%.
Design and writing are the sum of details. One percent is noticeable, and it makes a difference.
