What is your favorite quote, proverb, or piece of wisdom?

If indecisive, choose one of your top favorites. And by the holy powers bestowed unto me through the machinations of this platform, I grant thee to even post more than one, too!

Two of my favorite are from Antoine de Saint-Exupery:

“What makes the desert beautiful is that somewhere it hides a well.”

“We do not inherit the Earth from our ancestors, we borrow it from our children.” (Also attributed as a Native American proverb)

I kinda disagree with the first one. Plenty of places which do not support humans are beautiful. And I don’t like the implication that to be beautiful, you must be hostile with hidden kindness underneath. I don’t know if that’s how Antoine meant it, though.
