I don't think it was an act of courage per se, but a decision made courageously.
Yes, I did cross the Rubicon in my mind. I knew that my friends would no longer be able to talk to me. I weighed that heavily, knowing how I would be talked about.... All the games and mind traps the GB puts in your head.
But I adopted a simple mantra for me, and it has worked out rather well. It is better to suffer in honesty then to wallow in dishonesty.
I have frequently commented here that there is no easy, dignified way to leave the cult. It is messy, stinky, sort of like the prison escape in Shawshank Redemption.
I saw that well after my JW exit, but of course, the most famous line from that movie resonates to any JW at the crossroads as to whether to leave or not.
"You can get busy living, or get busy dying."
For JW's considering leaving, here is a better quote to consider, and its damn realistic too (from Shawshank)
"Andy Dufresne (insert your name here) - who crawled through a river of shit and came out clean on the other side."
