This is really an interesting thread. I was raised a 4th-generation-JW and I see so many descriptions fit me. Truly, there were some good things like learning to give a public talk or sitting quietly for some time and concentrate on a boring topic.
But I think that severe damage has been done. I have to admit that I am not always sure if it was my parents, the JW or the mixture of both.
I's already been said: what others think of me is always on my mind. I too have to prove my point right even when it's marginally.
There is a lack of self confidence; the task to do things good but to stay humbly in the background: "Was not a big deal." That would do well in the congregation but gives you problems at work when others benefit from your achievements.
Having always been an outsider I have problems to behave in a social environment. I feel that I still behave strange.
I have problems to make decisions because I am not used to. When there were questions we used to look it up in the WT Index. That also touches moral values. I think I can't really say what's wrong or right on my own.
Someone on a German board called it "social inbreeding". You don't get new views and cannot get futher.
I am glad that I live in the Internet era and that I found out early in my life. Now, I am working hard and hope to overcome some things. But I'm afraid that the impact of a JW childhood will always be there.
