One of our elders was one of the biggest ministry time wasters that I knew - he actually made our pioneers who had long mastered the "pioneer plod" look industrious - he was the type who would assign the territory ( eventually ) and then spend whole mornings driving around the territory making sure "everybody is OK" and basically using every dodge under the sun to knock on as few doors as humanly possible yet still count his time in full.
He had an evening insurance / loans door-to-door collection round and a couple of times he had car trouble so I drove him around in my car. What a contrast - he virtually would run from door to door - knocked loudly - no hanging about at all - shouted out directions to me & kept asking me to speed up. He wouldn't even stop for a take out coffee or toilet break ( the round took about 3 1/2 hours ). I couldn't help but think about the incredible contrast with his apathetic attitude to the "lifesaving work" and when he was doing something that actually was productive.
