I have this vivid memory of being a child in the 1980s when we had a CO visit. He stood up there, held up an Awake bound volume, and said that reading a year's worth of Awake magazines was equivalent to one year of a college education.
That "fact" was still being repeated 15 years later when I was a young adult. It wasn't until I started waking up that even the concept of challenging such an "established truth" became possible. It seems absurd to me now in hindsight that the 150 or so people in attendance would just nod along approvingly to such a ridiculous proposition.
As far the the TMS goes, it was of marginal utility. I was in a Spanish congregation and I suppose it forced me to learn some of the finer points of the language that I might not otherwise have had the occasion to drill down on.
