The question for me skips a step; the drive which brings one to a "creative-position" to begin with. Unless art is an income, in which case commercial considerations are a smart necessity, I don't think there's any need to look beyond yourself.
I can speak for myself in that I have yet to release (not create mind you) an album that didn't come from an undefined need: As the Germans express it so profoundly, from a "sturm und drang" to create. I have indeed made albums for the sake of creation, working with music etc. and shared parts, bits and pieces of those, but I could never bring myself to released them as such. The stimulation and excitement, the emotion of working on those is simply different.
Any other consideration than the "need" could result in very fine craftsmanship, but usually find it lacking in expression and emotion. I know this is a very personal view and I don't mean to write this as a motivational or "rule" for anyone else but myself. Which is another thing about creative expression; it follows such private motivations that when true to those, there's no such thing as invalid, averse or wrong. In the same way that there's no such thing as a bad piece of personal creativity. I might not like it, which is another thing entirely, but true personal expression cannot be bound by the same rules that apply to craftsmanship or professionalism.
So; if you "do it" for fame, I consider irrelevant. If that is ones personal drive, one strong enough to exceed the sum of creativity and craftemanship then the resulting work (or art if you will) has validity for me. If I like it or not is really just taste.
Despise as such is too strong a word for me to use, but I might understand what you mean. I used to feel that too when younger, the arrogance of youth in my case. These days I try to concentrate on what I like. I might not get exposed to new things so often any more and "what-I-like" is more narrow than ever but I have let go of the idea that simply because I like a narrow slice of a certain genre means the rest could have no merit.
Good luck with the writing!
