my bibliography though you can see where my favorite genre to write has been cyclical.
From 1995-2001 I wrote pretty much all sci-fi. From 1997-1999 that included some Transformers fanfics as well.
From 2002-2006 I wrote almost entirely literary fiction.
But at the end of 2006 I wrote a series of YA stories because everyone else was doing it, so why not me?
In 2008 I wrote my final literary novel (to date)
Then from 2009-2010 I wrote mostly superhero stories with a couple of more mainstream sci-fi ones mixed in
In 2011 I wrote the Chances Are series of thrillers
Then in 2013 it was back to superheroes with one paranormal thriller.
And my reading habits are largely reflective of that as well. Up until the new millennium I read pretty much all sci-fi. Then in 2002 I read mostly literary fiction. That was mostly the case until 2011 when I started reading old school mystery/thrillers by Raymond Chandler, Lawrence Block, etc.
On my old blog I tallied up the authors I read last year. Besides myself Arthur C. Clarke, Kurt Vonnegut, and Ian Fleming dominated the list, mostly because they were on sale. So that's pretty much a mixture of sci-fi, literary, and thrillers right there.
I have to say versatility is a good thing. I know they say to read a lot in the genre you're writing but it's also good to see what's going on in other parts of the world. At times I've read stuff I wouldn't normally like chick-lit and romance mostly just to see how they do it. If you can fit that in I think it's a good idea because it broadens your perspective. As old NBC commercials used to say, "The More You Know." So don't get too stuck on an one genre unless you're getting paid a lot of money to do so.
