Nowadays, the organization points to all the cautionary (hedge your bets) statements about 1975, but at the time, if you were a loyal dub, you were expected to believe in that date and adjust your life accordingly.
Kingdom Ministry, May, 1974, p. 3 (available via the WT CD library):
"By carefully and prayerfully examining our own circumstances, we also may find that we can spend more time and energy in preaching during this final period before the present system ends. Many of our brothers and sisters are doing just that. This is evident from the rapidly increasing number of pioneers.
Yes, since the summer of 1973 there have been new peaks in pioneers every month. Now there are 20,394 regular and special pioneers in the United States, an all-time peak. That is 5,190 more than there were in February 1973! A 34-percent increase! Does that not warm our hearts? Reports are heard of brothers selling their homes and property and planning to finish out the rest of their days in this old system in the pioneer service. Certainly this is a fine way to spend the short time remaining before the wicked world’s end.—1 John 2:17."
