I heard this come from the depths of a septic tank:

“If you’re really a mean person you’re going to come back as a fly and eat poop.“

– Kurt Cobain

Then I thought I would take my own advice and go with a kinder, gentler quote:

“Spend some time observing babies. They don’t work; they poop in their pants, and they have no goals other than to expand, grow and explore this amazing world. Be like that baby you once were, in terms of being joyful.“

-Wayne Dyer
