Here's an example of how AOW helped us. Perhaps a similar rationale might apply to one or more of you.
My wife and I have been OW certified for about 3 yrs. We are in our 50's. My wife is a much better swimmer than I, but I have a long, continuing history of athletics (soccer and skiing at high competitive levels). I am more adventuresome and physically self-assured than my wife. But, we both took up diving at the same time as a sport to do together. And, I emphasize "together."
Now, I had no qualms pushing my own diving depth gradually toward the recreational limit while continuing to learn through the experience of repeated diving. My wife, on the other hand, worried about going beyond 40-50 ft. That worry became an obstacle to our growth as divers. The solution we elected was the PADI AOW course. The navigation and deep dives were great confidence builders for both of us and we did them together. Knowledgeable, reasonable confidence is important. It probably matters little how the confidence and knowledge is achieved. Hiring an instructor just to teach navigation or deep diving would do just as well for some people. Getting the info from, and diving with, a trained friend might be even better. In our case, AOW was just the ticket, plus we did 5 dives with an instructor all of which were vastly different experiences underwater. Each was unexpectedly fun in its own way.
However, neither my wife nor I in any way consider ourselves "advanced" divers. "Advanced" divers are those (a) who have done a lot of diving and (b) are good at it. I qualify at the high end of such a scale applied to skiing and will never approach that level of capability for diving. But, it is a goal, nevertheless.
