Come and work for one day? Travel at you own (considerable) expense, stay overnight at an expensive hotel, arrive early on site and put in a 10 hour day. Stay overnight again, at your own expense. Travel back home, at your own expense.
When you return home, ask your bank for a loan to cover the week's secular work that you missed in order to put in "one day" at the Bethel project.
Watch more JW videos about giving more donations. Attend the regional convention and puzzle at the spiralling "costs" (Watchtower per person stealth tithe)...ditto that at the next circuit assembly. Listen to the prompts to donate more by the CO in his visits. Donate, donate, donate, give 'till you bleed dry.
Now ask yourself, how much money does the gambler put into the machine before he has a lucid moment and realizes it's better to "cut your loses" and get a real life?
