To be honest, being a faithful Witness kept me out of a lot of trouble in my teen years. I did absolutely no drugs, and didn't drink. It also helped me to be a good speaker and not afraid of speaking in groups or being intimidated when giving presentations at work. Understanding things like gestures, eye contact, and being clear and using material that fits the theme actually help in the "real world."
On the other hand, I still find myself not fitting in with people who are not Witnesses. My therapist has helped with this immensely.
I also wish I could have played sports and gone to college immediately out of High School. But why would you want to get a job at a restaurant with a "Going out of business" sign in the window? I mean, Armageddon being so close and all.........That was over 20 years ago.
