In the mid 1960's a non-jw uncle of mine was at high school and enthused about the woodwork, electonics and metalwork he was enjoying. When I asked mother about it she said "oh don't be silly, Armageddon will be here long before you go to High School". As it was I enjoyed high school but left to pioneer as soon as I legally could in 1972 (aged 15 and just in time to pioneer before the big A).
I know the WBTS, in league with my dumb parents, buggered up my life but many deny that the Watchtower Society promoted this kind of thinking. If the following statement is not aimed at making teenagers quit school what is it?
If you are a young person, you also need to face the fact that you will never grow old in this present system of things. Why not? Because all the evidence in fulfillment of Bible prophecy indicates that this corrupt system is due to end in a few years. Of the generation that observed the beginning of the "last days" in 1914, Jesus foretold: "This generation will by no means pass away until all these things occur."—Matt. 24:34.
Therefore, as a young person, you will never fulfill any career that this system offers. If you are in highschool and thinking about a college education, it means at least four, perhaps even six or eight more years to graduate into a specialized career. But where will this system of things be by that time? It will be well on the way toward its finish, if not actually gone! (Awake! 1969 May 22 p. 15)
