I would have to agree with previous posters in saying that lying to a householder and yourself pulls you out of the ministry all together. Being awake and going door to door is impossible considering you know the message is bs and trying to sell bs is mentally stressful. We even tried telling the householders the truth about the org but we discovered there are much better things one can do on a Saturday morning than banging on doors.
When the wife and I realized this we just stopped reporting time. From one month of 11 hours, then to 4 hours the next month, to nothing. Didn't even feel guilty about it. Why should we? They lied and we fell for it.
