It is, for better or for worse, the bending of personal will. And while some artists may attempt standards such as academic standards, commercial standards or intellectual standards, there will always be significant creators who don't give a hoot about standards at all.
The main thing you need to think about is process. Your process. Individual decisions cannot be taken from some list. They are the result of your previous moves, including your errors. They are also the result of your noted winnings. This is how you-as-a-person becomes you-as-an-artist.
Funnily, in youth, we are often rigid. We tend to think there is some secret, some Holy Grail that will have great art appear on our easels. We may even dream that fame and fortune will arise from this correctness. As we grow older, we realize just how limiting were our earlier conceptions. Art is something else. Art is fluid, transmutable, open ended, never complete, and never perfect. Art is an event.

PS: "Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep." (Scott Adams)
Esoterica: There are two kinds of students--recipe takers and recipe fighters. The former listen to the instructor, try to get it "right," and often succeed in doing so. The latter strike out on their own, pay the price of rugged individualism, and fail often. In art, it's all about failure. In art, the journey outshines the destination. In art, mistakes are golden.http://www.painterskeys.com/
