Thanks for sharing your life story!
I don't know of Suen, but I have observed a similar pattern many times in the JW world. The WT has a way of attracting a certain type of person who has a phenomenal way of reaching people. It is definitely a gift, and these ones would make great salesmen or politicians. They have a way of speaking with the greatest of confidence and can sell iceboxes to to the Eskimo. It's more of a motivational sales skill rather than a religious one. The WT would have collapsed many times over the years if not for these slick salesmen.
Other organizations have the same sort of person. I watched a video recently about a MLM scheme from one of their motivational sales meetings, and I thought, Yep, it's the same thing.
