I would think that a great way to do direct learning for essay writing would be to PhotoRead (without activation) a bunch of books filled with essays on various topics. Or, check to see if you can find a site on the web that has a reputable, quality store of argumentative essays by scholars. I'm sure they exist. Once you do this, you will definitely need to practice essay writing over and over again until you truly refine your systematic application of the subconscious knowledge you've gained. That would be the equivalent to activation, it seems to me :-)
Correct me if I'm wrong, as always. I'm still learning!
