> Speech also proceeds under the whips of two tyrants: time and memory. Our memories aren’t nearly capacious enough to allow us to compose and precompile each sentence before beginning to utter its first syllable. Instead, speaking is like driving with a general sense of the destination, but no clear route planned—we utter the first syllables of a sentence while taking a leap of faith that we’ll be able to choose the right words en route and formulate phrases adequately as the words tumble out of our mouths and bring us to an intersection in our thoughts that demands our next move.

I have read (but can not presently find a source to confirm) that Edsger W. Dijkstra was raised by a grandmother who forbade him to begin speaking a sentence without first knowing its conclusion.
