I have a lot of scraps of paper taped up around my desk, full of scribbled insights. I've gathered them through the months, and put them up to remind myself of the things that are important in life: making wise choices, loving people, living for God. One of them says, "Our default assumption is that people who choose their words carefully are quite smart."
It needs no explanation, and lines up with a proverb.
"Better to be thought a fool than to open your mouth and remove all doubt."
Also self-explanatory.
When you're in a creating position, think carefully about what you say and make. It pays off in the long run.
