Interesting how i share the same experiences as many of you. I stopped attending 7 or 8 years ago. First because i was lazy and not motivated, and later after enlightening myself decided to completely quit and never go back.
It has been an amazing decision, all the guilt trips associated with never making the cut and never being able to produce what the society demanded ( hours, etc) are now gone. My immediate family are JW which is the only drawback of the whole situation. My relationship with them is lackluster, but still good enough that anybody gets along.
I'll admit that although i had some cognitive dissonance when i was in, i still believed that the Watchtower Society was somehow enlightened and wise and somehow had insight into the future. The key as i understand now to burst the JW bubble in your mind, is to critically think of the activities and reasonability of the Governing Body and their actions - this is the first road block. As long as one believes they are somehow informed by God, they will likely remain faithful despite other inconsistencies.
Reading an insiders report on the GB by Ray Franz was critical for me, because it made me realize that the GB are just a group of out of touch old men, who simply grasp and claw at things to try to keep the house of cards together. They are not enlightened, they simply make decisions in the same manner that other corporations do.
