I will not tell anyone they shouldn't be reading this littera-trash. I will say that you should not heed the advice contained therein--go ahead and read it, if you view it as entertainment or are preparing for the time you might be forced or dragged back in or to help someone out.
As for that lame "I cut back my work and was able to do more for Jehovah" excuse, I don't know how many times I heard that crap. What they leave out is that this leaves them with no room for problems. What if the government decides to create a fake energy or food shortage in your area? If you have "surplus", you can plan ahead for that. Getting candles, batteries (I prefer the rechargeable ones), quality flashlights (the best ones can cost more than $150), lanterns, and battery chargers now will protect you when they start doing rolling blackouts. Can't happen? California already had a fake energy crisis started by Enron in 2000. And, if gas and/or food gets too expensive because of a fake shortage (or a real one), you can get a backup plan.
Also, if I could live on 20% less now, now might be a good time to invest that 20% in hard assets. Durable goods are the priority. Do you have crap that is on its last legs? Now is the time to ditch it and get good products that are going to last 20, 30, 50, or more years so, when your currency becomes toilet paper, you will not have to replace things so quickly. Once that is done, physical possession of gold (or preferably silver, which is currently underpriced compared to gold) will provide a measure of security. It might not provide security "in Jehovah's day" (and neither will trusting in Jehovah). But, if your bank closes and you lose your money in it, or hyperinflation destroys the value of your money, your gold and silver will be able to get you through it. And, even if not, with gold at $1300 an ounce, fair value for silver is around $80 per ounce using the standard 16 to 1 ratio. It is now under $30, a steal.
Will your "treasures(??)" in heaven appreciate like that? I don't think so.
