To continue with Blondie's excellent comment about "having too much invested..."
One of the most important principles of investing is to know when to cut your losers short - thereby taking a LOSS - and to let your winners run.
JWs are "invested" in a spiritual Ponzi scheme with "Brother Bernie Madoff" - the WTB&TS.
All of the so-called "profits" shown on his ledger sheet have been invented - for example, all the "prophetic fulfilments" that occurred in 1919. Completely unsubstantiated, baseless claims that get the ignorant rand-and-file all revved up and ready to invest another 10% of their lives. When we look behind the curtain, we see a stack of decomposing corpses who based their hopes for the future on earlier, pre-"new light" statements.
"Millions Now Living Will Never Die" - in my pants!
Jehovah's Witnesses may not be the happiest people on earth, but they certainly are among the most unskilled "investors" of all time, letting their losses run and cutting their profits short.
"We have only ONE resource - our lifetime - and from the wise investment of that time all other profits flow." -- Saint Natas, 2010
