In the novel "Flowers for Algernon", a mentally challenged man suddenly starts getting smarter after getting a medical procedure. He gets so extremely smart that he can "see" how everything is - and then his condition slowly reverts. Towards the end he loses all his intelligence, WHILE KNOWING that he is losing it.
That is my experience in the past 2 months after leaving FB. I could physically feel my brain cells rejuvenating. I could "see" how society is, the way Neo sees the Matrix. I had profound thoughts, although I shared them with no one.
And now I am posting again, slowly pulled back into the cesspool knowingly.
The best way to quit something is to hate it. 2 months back, a series of incidents led me to hate FB, which felt very good.
Now I try to bring back that hatred and it is not working.
