In the years 1970-1975 I certainly was not counting down the years till Armageddon. I was focused in dong well in my grade school courses and in doing my hobbies. In 1974-1975 I knew that the WT was not saying that Armageddon would definitely happen in the year 1975 or even by that year. I also knew that the Bible does not say the hour it will happen, nor the day, nor the year, nor the decade, nor the century.
To me at no time in my life did the New World under Christ, nor Armageddon, nor the Great Tribulation appear to be within two years. I never perceived any evidence that it was ever that close. As a result, up through the year 1975 I gave nearly no thought to the timing of Armageddon except when reading WT literature about it (and I primarily read the literature because the WT said I must or should). When I was in 1975 and thus a young child in grade school, the JW religion (in regards to praying to Jehovah God, studying the Bible and other WT literature, and attending the kingdom hall meetings and going out in field service) was pure drudgery to me. I wanted to do what was fun and/or interesting to me, and worship (other than practicing good morals) was neither to me.
Regarding disco music I greatly like the sound of the popular disco music I heard on the radio and on the TV called "Solid Gold" and I still love those disco songs, including numerous ones by Donna Summer. In the early 1980s I was thus offended by WT literature saying all disco music is bad (and thus even the hits in the Saturday Night Fever soundtrack) and must be avoided and that JWs should never go to disco clubs discotheques). I continue to love those hit disco songs and after I moved out of my mom's house I purchased record albums, cassette tape albums, and much more recently a few CD albums of those great songs.
