If most believe they are happy in their ignorance, it's definitely a waste of time.
Most wake up on their own. And it's usually some crazy internal change or article/talk/doubt/etc which does it. External exchange has very little to do with it.
The research into things comes after the awakening not before. Most have to have that wait, huh, moment from something said in an article or a talk.
What anyone outside the internal sphere said would have meant nothing to me. You're just Satan trying his best to mislead in my mind. JW think.
