I also want to be a writer. Of course writing is not easy. I have to look for references first as well as a quiet enough time to write. Writing and reading are my hobbies. So I write because I like it, but sometimes I also want my book published, and I become a writer.
I always look for the right time to write, if my mood is peaceful and serene, I always write. But, if my mood is not good, I won't write, because it makes my writing a bit bad and I can't concentrate.
