Try लेखन something आप come up with. I have written many पुस्तकें based on experiences and dreams that I have. Sometimes I don’t even pay attention, I just wake up some mornings and think wow, what a twisted dream, I think I should write it down.
It sounds like आप are trying way to hard. Write for fun, write about anything आप want. लेखन is a great way to express your feelings. Don’t just write about वैंपायर because Stephanie Meyer wrote about vampires, and her book became a best seller. If every लेखक wrote about वैंपायर just because Stephanie Meyer’s पुस्तकें became a best seller, then people would get bored of vampires, and not read your book
