This question is somewhat linked with Should you read your own genre?, but I believe it is distinct or at least approached in a different way.
I am a sucker for sci-fi/fantasy and read nearly exclusively within these genres. I would love to write in these genres, but do not seem to be able to.
By now I am an “expert”. I have read thousands of them, so writing within the genre should be easy and second nature, yet I can’t.
Every creative idea I have seems to go toward realism, autobiographical, spiritual, poetry, techninal and academic writing.
I really would love to write what I read.
I guess this block could be because I know plots and stories so well that I can smell the stench of an overused idea, or even a seldom-used concept. It seems like my mind goes blank because I know it all. Or I might be afraid to be measured against giants I admire, I do not know.
I am not sure of the solution, or how to overcome this block, do you have any suggestions?
