As a JW I remember the irony of the Watchtower using the scripture you quote contrasting hope deferred with fulfillment of hope.
I also remember staying in California about thirty years ago and hearing that the bros around there at the time were getting impatient because of not seeing "the end" as promised by the WTBTS.
Deferring hope is all the JW org can ever do, it's a big con trick. Each generation of Watchtower believers, and there have been five of them now, forgets that the earlier generations also lived with their hopes permanently deferred.
People eventually tire of hearing false hopes and I think the org is now ignored because of being a false prophet as the decline in numbers is beginning to show.
Yes LTS life is too short to waste on useless religion.
