My friend makeitplain has collected sayings from years of travel. He puts them in jars, stripped of context and attribution, and sells them on his website.
"[W]isdom is not a book of doctrine, but a journey of conversations...What matters is the brief instant when someone looks into your eyes and shares words with you. Every conversation holds a deeper message that is meant especially for you. Do not question it or reason it away; treat it like a message in a bottle."
