IF the WT would happen by chance to guess it right on one date of their predictions, they would still be like the broken clock -- wrong 11 times for every time they are coincidentally right.
Well to our group of "mentally diseased" apostates.
I've been doing the JW thing since childhood and got dunked as an infant (almost) in the mid-60's. I very well remember their first prophetic date that affected me. (There were plenty of more prior to that one.) It was the 1966 revelation of the 6,000 year chronology that "strongly indicated" that 1975 would be the conclusion of 6,000 years of man's creation. YES! It meant Armageddon was imminent!
It was followed up by the Awake! magazine article in the May 22, 1969 issue (things were really getting "close" now) stating that youth in from high school would not have sufficient time in this system of things to complete a college education. YES! YES! The End(™) must be very, very close! "STAY ALIVE 'TIL '75!"
Guess what? None of what they predicted (prophesied?) ever happened! 1975 came and went. (Of course sitting in line for gasoline at the exorbitant price of 75¢ per US gallon made it seem like the "end of the world" was coming as did driving only 55 mph and 18% interest on a mortgage.) Still, ZIP! NOTHING!
BTW -- nothing of what they predicted about 1914, 1925, 1940's, or "before the end of the 20th Century", ever happened either! So far, the broken clock has a much greater success rate than the WTS/GB!
**************
Since I suspect you are younger than I am upon awakening to TTATT, my first suggestion would be to PLAN NOW for the remaining future you have. Not only could I have finished college, I am retirement age and have finished one career. Fortunately, I am not like many older JW's that have attained this age but are broke and without a decent pension or savings. PLAN AHEAD FOR YOUR FUTURE! You will not see the Panda Petting Paradise that you have been promised. Quit holding on to false prophecy.
Also, be "easy" on your family that is still in. You won't awaken them by dumping everything you have learned regarding TTATT on them all at once. It is a gradual process, as you no doubt discovered yourself. Drop little hints. Ask "disturbing" questions. Force them to investigate the "Truth".
Good luck! Glad you're here!
