The thing that makes you hard to categorize is the same thing that makes you hard to replace.

Being easy to describe and being easy to replace tend to travel together. The odd combination of interests that makes you awkward to summarise is the same reason nobody else produces quite what you produce. Early on it feels like a disadvantage, since categories are how people get picked. Later it becomes the advantage, because what is wanted is the specific mix only you assemble.

Stop trimming the part of your work that does not fit the obvious label. Put two of your unrelated interests in the same room this week and see what comes out of it.
