I understood your question as a description of this situation: the combination of you/someone having a constant desire for "more money" and the other party turning you down by default.
That sounded like a sad cooperation to me.
For you/someone: the other party is never interested in an constructive cooperation/dialogue. For the other party: you/someone sees the work itself as second (or less).
But as I now read you enjoy it by itself, I misunderstood.
i'm asking for money because i think what i'm doing has value not because i didn't like doing it. And the fact that people like it so much they're ready to pay for it makes it even more enjoyable to me.
