I can remember all the while I was in the cancer that they would trump up the value of pious-sneering. One of those was the "joy" of serving Jehovah full time. They would always have these fantastic stories about how they had obstacles that they foolhardily disregarded, or that they got all these people into the cancer.
This is full of rubbish. First, when you have stories about the "joy(??)" of helping someone else doing the same work you are doing, are you really benefitting yourself? What do you gain when you bring someone into the religion? Does doing so make Jehovah more eager to actually do something for you? Rather, does it make him tend to expect more out of you? I believe that it simply makes Jehovah do nothing except laugh while you are getting nothing, then point out some stock example in a Washtowel rag or the LIE-ble and expect you to do the next level. Do that, and expect nothing.
While I was in, I would see the pious-sneers showing up usually 15 to 20 minutes late. And not because they had secular work that let out late, either. Because they are struggling to get up. Some would already have been out since 6 in the morning, after having a boasting session the previous evening. They don't feel like being out there, but they have their damn cup of coffee that they rely on to get going. I think coffee should be because you enjoy it, not because you need it in order to carry on a schedule this draining.
And never mind screeching around. I have seen pious-sneers that were capable of walking 6 km/h doing less than 2, in fair conditions. There is more wasted time waiting around "gathering things", errands, and so on than time spent knocking on doors. And when they do knock on doors, most of them are hardly eager to talk. Usually they will knock twice, then take off. How many times I got past this point and the householder yells out a second story window "Who is it?". That always pxxxed me off, unless they retorted "Not interested!". True, they have call books full of calls and potential studies--that usually advance 5 or 6 lessons before they are perennially not home or lose interest, or bumble on for the whole book only to not have them show up at even a single boasting session. Hardly "joyous"--and even if they were all getting baptized, again it comes down to "How am I going to benefit? Remember, there is no point in doing this if you are not going to benefit personally.
Then there are those fancy book bags I have seen advertised. I read some of the reviews that said "This bag gave me a whole new zeal for field service". Now, I don't see how that could happen. Usually, you get the feeling of relief when a product solves a major problem. Usually, the problem isn't the messy book bag. It is the mechanics of door to door, and if everyone's bag was perfectly organized, there would be so much less wasted time that most pious-sneers (and everyone else) look forward so much to. I, for one, would rather waste 15 minutes fumbling for my rags and call books than spending that same 15 minutes talking to someone that is spitting blood into a mayonnaise jar the whole time.
In the end, there is no joy either. You do full time service to Jehovah, and you get nothing. Most pious-sneers that have been doing it for a long time are destitute and in relatively poor health. You get to be about 85 or so, and realize that most of what you were doing was a complete waste. People you "brought" in are out. Or, you started maybe 500 studies and not even one got past the middle of the book or saw the inside of the Kingdumb Hell. Financial troubles are plentiful, and you are struggling with health issues. Yet, in your old age, the congregation looks down on you once you become useless to them. You produced no value, and are now reaping.
Perhaps as bad is what happens if you wish to stop. Suppose you dedicated your soul to Jehovah (your life, same thing in their eyes), and fully intended to do all you could for him. You got baptized and started pious-sneering to uphold your dedication. Some time later, Jehovah fails to fulfill his promises to you. What happens when you decide you no longer wish to pious-sneer? People develop health and money issues, too, that cause them to reasonably and prudently stop pious-sneering. Not to mention the danger that, if you wish to later dedicate your soul to Jesus (or Satan, as is the case more of recently), it is not available because Jehovah has full control and will not relinquish your soul. Right on this life, you get hounded when you stop pious-sneering. Adjust your schedule so you can keep pious-sneering--that is the stock advice. Rarely to never does it work.
And for what? I never saw the potential for joy in pious-sneering. I got enough doing 20 hours a month, and that was not exactly joyful. To me, pious-sneering would only amplify the problems I had with 20 hours a month, and more than 3 times worse. As I saw it, you are not doing anything new--you are doing more of the same old thing. Not joyful.
