Never being baptized. I think that I had the necessary brains, along with the friendly rivalry my high school friend provided, to become an architect, an engineer, something of that sort. All I needed was the confidence, something that I believe that being JW and being raised by a single, over-protective mother kept me from gaining.
But, as you say, who knows what the ultimate outcome would've been? Better to live the life now and look towards the future.
