Awake! 1969 May 22 p.15
"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 high school 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!
