Public speaking I think is the one thing that I have to give the WT credit for. Also, as a JW I was very good at preaching house to house. I would talk to anyone and would not take no for an answer. I would talk to people some other JWs shied away from.
My process of surviving such horrible experience of so many people trying to make me fit a mold I am not made for gave me strength, resiliency, and confidence in who/how I am.
The fact that the WT is so full of phonies claiming that their magic Jehovah does wonders, seeing the hypocrisy of so many JWs, including many in positions of authority, and growing up with double-faced abusive JW parents, has given me a great way of not buying into people's bs. I think that's the biggest gift, seeing through so much hypocrisy and nonsense and people pretending to be happy. God, did I hate those stupid glazed happy faces!
