We end the briefings at my airport with a "quote of the day." It's meant to be something insightful, inspirational, thought provoking, or just something to build morale. We've also been asked to submit quotes to be featured as the "quote of the day." I've been introduced to a few I like from Johann Christoph Friedrich von Schiller:

"Against stupidity the gods themselves contend in vain." – (Talbot in Maid of Orleans)
"The voice of the majority is no proof of justice." (Sapieha, in: Demetrius)
"Live with your century but do not be its creature." (From On the Aesthetic Education of Man.)

Any other suggestions?
