Roosh just called someone out in another thread regarding sanctimonious tone around "secret knowledge" - but how else do you do it?
You don't overthink it and you don't overdo it. You just drop a couple of poignant sentences that sound like they're common knowledge and anyone who wants to follow the trail or PM you for more insight is free to do so.
Roosh is correct that people don't like to be told "well done, kid, you reached 10% of my power level" but you're also correct that it's very hard to bring people along when they've started long after you did. I remember maligning people at the JQ level of progression as losers and bigots just as I have been maligned by others once I reached that stage of awareness.
I now place a very limited value in secret knowledge. Previously it was something I valued because I felt I needed a guide of what to resist against (evil) but now that I have a spiritual true north (Christ) there is little value in focusing on evil rather than good (God).
