Here's my take on how the Society could increase it's ranks 10x.
Start from scratch and go back to Bible basics.
Eliminate speculation. Every last thing in life does not need a rule on it. Recognize that there is a grey area.
Cut meetings down to Sunday Public talk. Wednesday Bookstudy consideration of WT and some Service points.
Make door-to-door optional for publishers and encourage people to talk about Jehovah when their HEART moves them to. Pioneers, elders and MS do the door-to-door.
Eliminate the name of the publisher from service report. That way they can keep track of the numbers but people will feel better about what they can do "not in comparison with the other". The elders will see who is reaching out.
Allow 'conscience matters' to really be conscience matters by drilling in peoples' heads to mind their own business. The last I checked I didn't marry Bro. Nosyashell.
Follow Jesus council to "Stop Judging". Don't just say it... REALLY stop. Accept that the judging is Jesus' job in the future.
Stop the guilt. This I think is the reason most people leave. I have NEVER felt commended and that I was doing enough even when pioneering and an MS.
That's all I can think of right now. I'M GOING GOLFING!
