A subject I (sadly) may have some expertise in !
If you are an old dude, what motivates you? Not sex, generally. The hormones decline and the performance goes........ well, limp (except for those wonderful blue pills). If you're a Witness, it's only done within marriage anyway and not as a hobby.
How 'bout food? Often, no. You end up on some god-forsaken diet, your digestion goes, your teeth fall out, diabetes looms large and your sense of taste may suffer.
So, what's left?
EGO !
Your sense of importance, of being 'somebody' (not a nobody). And the desire can intensify as eventual demise approaches - the ultimate loss of self/importance. If you are Hitler, Stalin or Mugabe, it gets intense.
It isn't always bad. You may begin to think of your 'legacy', of leaving the world as a better place, in other words, being a statesman. Even if you're some grubby politician, you may want to do accomplish something great and memorable, like LBJ did with the "Great Society" , in contrast to his years of corruption and ugly behavior.
Like Mr. Banks in Mary Poppins, you want to 'make your mark' on the world, while you still can.
So, what motivates the (old) Governing Body of Jehovah's Witnesses? They cut, they downsize, they layoff, they reduce. They see the malaise..... and where's their opportunity to 'make their mark'? To do something lasting and good, unique to them as an individual?
Well, it isn't there. It can't be. The money and zeal are draining away and they have strong prohibtions against any organized charity. There's also no 'Witness College' or Watchtower version of BYU. It's that 'The End Is Too Close' straitjacket.
It must frustrate them terribly. The only other Old Cabal that I know about in a similar situation are the collective leaders of North Korea (with their Spiritual.... Oops! I mean "Worker's Paradise"). They can't grow, they can't win a war and their organization is decaying.
Currently, they are drifting into outright fantasies, talking about reducing Seoul to ashes in a few minutes and defeating the US.
Maybe the Governing Body will follow suit and drift into deep fantasy too. Perhaps their egos demand it.
