My parents started studying to become JW in the late 1950's and I was raised in it.
I believe at the time the belief was that the tribulation had started in 1914 and been cut short and Armageddon could start at anytime. In the late 1960's they became aware of the 1975 teaching. The 'Truth' book was released and I believe there was a change to a shorter study period before baptism. This made for a sense of urgency in our family for preaching and worship as the time was so short.
Did you feel proud to be a JW back then?
I didn't feel proud to be a JW i felt lucky, fortunate that my parents had responded to the message as I probably wouldn't have. They felt concern for people and made efforts to do more in the preaching and be a more theocratic family, making a more simpler life so they could do more in the 'truth'
Was the society as strict as it is today?
society or no society my parents would have been strict. I think faith makes one act in a certain way.
