I didn't go to college and of course, "higher education" was never recommended. Still, I never felt terribly deprived because of not going further in my education.
Yet, I did wish that I could've had "normal" aka "worldly friends". I wish that as Witnesses, we could've been better integrated with other people. Instead, we were taught that everyone else was going to (ultimately) die simply because they weren't Jehovah's Witnesses and we were (ultimately) better off not getting close to them.
It's too bad that Jehovah's Witnesses are so close minded and self-righteous.
