OK, if we're really listening, everybody is a teacher.
But this thread aims to collect sayings that remind us -even when our attention is weak- that wisdom has no exclusive contract with buddhists, religious systems, or real characters for that matter. Lemme start with these 3:
"Do not wait for the last judgement. It takes place every day"
Albert Camus, great teacher of cause and effect
"I yam what I yam"
And a great lesson in impermanence from the latter-day-ancestor, Yogi Berra:
"The future ain't what it used to be"
