If I could really subconsciously influence the minds of others through writing, I would include in my writing a lot of random bullcrap just to throw people off balance, and to distract them from the really influential bits. That way, they'd be reading something silly and then *WHAM* from behind a corner, enlightenment (illumination?) *SLAMS* into them.
If I couldn't, I would express myself through such indeterminate bullshit that people couldn't quite be sure I wasn't doing something clever, and then just wait for them to fool themselves.
In any case I would also drop noncommittal yet suggestive hints like this one.
