Well - having read this thing front to end now I'll say this.
I plan to continue reading. Be it books, fora or the back of a cereal box, I'm gonna read it. I plan to dive more often. I am also taking a Nitrox course as a minimum. Mostly because I want the advantages Nitrox offers. Will that make me a better diver? Dunno but it's what I want to do. Been checking out rescue diver as well.
I got certified in 2000. Didn't do a single dive after certification (mostly because it iced over about a month after I got my card).
AOW in 2011 - almost a full year after initial certification. Learned quite a bit. Mostly because our "deep" dive was to 117 feet and the viz was in the neighborhood of 9 inches. What I learned is that the largest asset I had as a new diver was the space betwix my ears. Both in and out of the water. I dropped out of diving after that. I did pick up the occasional magazine or book though.
Fast forward to this spring. I'm dating a new lady, she showed interest in scuba so we signed up again. The second I hit the water it came back to me. It had been about 10 years since I dove and I performed all the skills to the instructor in one shot, no repeats and If I may say - my buoyancy control was better than it was back 10 years ago. Probably because I knew better now what I wanted to do and why/how rather than just parrot the instructor well enough to pass.
It's lit the fire under me that now as an older student and MUCH wiser, I know where I am and where I am headed.
I find the classes fun because I LIKE my instructor (went back to the same guy), I like the people that dive at the shop, I like learning. I find these boards interesting because I can expand my exposure to how things are done. I don't claim to be DIR but I can see a lot of things there that REALLY make sense to me - re gear config. I learned that here/reading and not because I saw it on a boat somewhere. That (to me) means that reading things like this doesn't mean you've learned or mastered a skill but it does have value. I'm going to incorporate that into the diving I do. If it works - I'll keep it, if not, I'll modify it till it does. That's learning. IMO and that's CONED.
YMMV...
