I was 21 in 1975. As 1975 approached I started having some doubts that Armageddon would come that year. It seemed the Watchtower was starting to be less definitive about the 1975 date, and it was hard to think something like that would happen, there were no big wars or other signs. We had a few earthquakes, but it was California. Life seemed to be just going on like normal. I had my first child in December and being a mom became my focus,, not worries about Armageddon.
By the time 1975 ended everyone realised that Armageddon might not come right away. Like many, I said I wasn't serving Jehovah for a date, so it didn't matter. No one questioned why we were led to believe it, we accepted it as being our own fault for "jumping ahead". It's amazing what you can get people to accept. We all got scammed but we didn't see it at the time.
