You're probably going to be disappointed, but it's likely the first.
I am practical about this. I really enjoy diving, but diving solely for the sake of improving skills is not my goal. A more appropriate wording of my goal would be "gaining the skills necessary to be able to explore areas which are currently closed off to me, and which will always be closed off to a huge percentage of the population". I know a lot of people are probably not thrilled about a person having that mindset, but I don't get the luxury of unlimited time in the water, I have to be judicious and more targeted. Gaining a skill for no reason other than having it, is less desirable to me.
Some people dive to train with a simple focus on improving their skills, while I get the desire to improve, I don't completely get the constantly only diving for skills improvement. I dive for fun myself, the skills come from frequency of diving and practical application. There's nothing wrong with wanting to dive for the shear enjoyment of diving.
Welcome to the fun house.
