Karma is a glimmer of truth in the complicated and intricate search for the answer to human existence. It's a spiritual guideline that mirrors the physical world: cause and effect. Which makes perfect sense. Push and you will be pushed, pull and you will be pulled, drop your juice box in the trash and you will be crushed by a four tonne wrecking ball.

Karma can be harsh, but the wrecking ball swings both ways. Consider this: shortly after launching the campaign, I found five dollars on the sidewalk.

"Instant karma's gonna get you / Gonna knock you right on the head / You better get yourself together / Pretty soon you're gonna be dead"

- John Lennon
