Maybe experienced is when you can do a long series of repetitive dives and not discover something new.
I know for me lately, about every 3rd dive I am coming up thinking ‘I suck.’ In fact, just a couple of months ago I thought about selling everything and getting out of diving all together after one dive trip. I am finding myself questioning my gear configurations, my skills, everything…I don’t know why…but after 500 or so dives, I am not experienced…not the diver I want to be…and it’s frustrating.
