This is why we used to prefer going to conventions we were not assigned to. It's much easier to listen to talks and experiences of people you don't actually know.
We had in our congregation a pioneer couple. Always crying poverty and somehow managing to get money etc from the brothers. One couple gifted them a car but they then pumped the generous couple for the money to pay the insurance. Then they managed to get a single pioneer sister to buy them new tyres for the car.
Eventually their money pumping ways became an issue and elders got involved. They moved congregations. 5 congregations later and numerous victims.
They used these two as an example in simplifing your life at a convention where he told us all that he could have been a millionaire but walked away for Jehovah and took up pioneering.
