An avid writer and a research enthusiast, I have worked in different fields of content creation including Novel, Informational, and Technical Writing. My experience taught me that working as a writer without love for research is like creating a document file without using a keyboard... Or maybe writing on a piece of paper using an inkless pen... or maybe both.
