Guest blogger Tony Piazza says you should write about something you know and enjoy.
There is nothing original about this tip, but yet sometimes authors overlook it to produce something that they view as "current" and therefore financially viable. For example, I am a mystery writer; it is what I know, love, and do best. I would not be good at writing about Vampires, Zombies, and teen love. My heart would not be in it, and a real labor to write. Undoubtedly this lack of enthusiasm would be reflected on the pages, and easily singled out by the readers. More importantly the critics would drive a stake so quickly into my work that it could never rise again!
Brilliant advice, Tony.
Agents, publishers and readers are looking for fresh and original voices, and fresh and original stories. Chasing trends will not create loyal, enthusiastic fans for your work.
