Learning Consistancy at our house

We recently spent 2 weeks with a zero tolerance policy.  Zero tolerance for not doing chores without being reminded.  Remembering chores had become very inconsistant at best and I was beginning to sound like a parrot.  I've not been a parrot since.  I always think I'm being consistant, but consistancy is the absolutlely hardest concept to follow and to instill in another human.  Now that everyone is remembering their particular chores, we are trying to follow through with some positive reinforcment without letting ourselves fall back into inconsistancy.
