This thread makes it clear that some of us were a better fit for the religion than others. I never had to lie because I really liked the trappings of being a Witness. Going to the library instead of participating in a birthday party was awesome. Not having to worry about dating was awesome. And so on.
I remember seeing them relaxed in their shorts having deep, exciting converstations about Bible prophecy, when the end was coming, etc. JWs just don't do that anymore. For one thing, most are incapable now; they don't even know their own doctrine.
I think the problem is that the sense of immediacy was eventually, inevitably, lost. 1975 was a blow to that. 2001 was a blow to that ("Wow, we're in the 21st century..."). 2014 is hopefully a blow to that (1914 + 100). So the Witnesses just don't see the value to thinking about the prophecies so much now. It's become a simple slog to the end, a death march, an endurance test where we try to outlast this old system of things and make it to panda petting paradise.
