Growing up it was a hit'n'miss thing, until one day my dad decided to study the "Youth" book with me for a couple of weeks
Every now and then we would get hit with the assembly-knee-jerk reaction, and do some more. It would petre out after a few weeks, though.
I tended to study a lot, anyhow, so I didn't find that a big deal.
When I married we were hit'n'miss, too, but would hit the cycle every now and then.
We studied the Wt for quite a while, but that dwindled to studying it for ourselves at the same time in the same room, before dying out completely. To be honest I was totally over-worked as an Elder. The only evening I wasn't doing some kind of studying was a Friday. After a long week at work you can imagine how that was spent...
