Interesting question.
I used to have a lot of diving goals. You know what they say though? Sometimes wanting a thing is more pleasing than having it. I've done most of what I wanted to do and now that I'm not teaching and not working toward any specific goal it's all lost a lot of it's excitement. I've never been much of a tourist and swimming in circles whether on a reef, in a wreck or in a cave just doesn't seem to do much for me especially considering the time, work and cost associated with it. I'm not a historian or a geologist and how a wreck got there or where a cave goes is of little concern to me...it's either cool to look at or it isn't. I still like to look some but it hardly seems worth it.
There are, of course some places that I haven't dived that I would like to. I had a trip planned to the west coast next month but I had to put it off. I'd like to do a little more underwater hunting. I did a little when I first started diving but haven't done it since and stocking the freezer seems like a fine reason to dive.
I still like to spend some time in the water just because it's a nice place to be and after all the training and equipment I've accumulated I find that I enjoyed my local quarry dives last year with my wife and son about as much as I've enjoyed any of the "big" expensive dives we've done.
I guess I've gone all the way around the block. After chasing certs, caves, wrecks, and even jumping into the dive industry up to my neck, I find that the very first diving I did right near home is about as much fun as any of it.
