As cliches go, the (paraphrased) doozie of: "Write what you like, not what you think others will like", has to stand fast as perhaps in the top 5 when it comes to writing. I believe that if any of us attempt to write for others expectations, several unhappy things are likely to occur. Firstly, you will not satisfy the readers. Secondly you will be unhappy yourself. Thirdly, it is likely to be derivative (an almost impossible task to avoid today, perhaps).
Ultimately I suspect you will get bored, dissatisfied or worse begin to hate the work, the ideas, storytelling as a whole, even (in the worse case scenarios) yourself.
I also tend to believe that deep down we all know when our writing sucks, or at least needs improvement. It's that niggling sensation at the back of the mind when you read it back to yourself and it just somehow grates.
So keep at your own work, your own dreams. The writing is the goal, the storytelling the accomplishment. Publishing is the icing on the cake.
