Discretion

"Like a gold ring in a pig's snout
is a beautiful woman without discretion."
Proverb 11:22

Or I like how the Message says it:
"Like a gold ring in a pig's snout
is a beautiful face on an empty head."

Pretty harsh, but that's biblical. Watch the words that come out of your mouth, that you write in pen, or type on the computer. Speak kindness. Speak love.

"Discretion will watch over you
understanding will guard you."
Proverb 2:11
