I'm often asked how often I write? Do I set a block of time aside? Do I write a minimum of X hours a day?
The answers - it varies, no, and not usually.
I write when I can first and foremost, and that's different every day of the week. (I keep a rather chaotic schedule!)
I will make time when the inspiration hits though, which means sometimes things will go by the wayside while I write. I'm not the faster writer (and an even slower typer) so it can take me days to conjure up one 2-3 page scene! Of course, there's times when my pen flies and I discover I've done five pages in three hours. And that doesn't just depend on my inspiration - a lot has to do with interuption, too!
I try to work on my next book at least a little bit each day, although this one will positively NOT be coming out next spring! This one is getting proper treatment, even more than the first five.
Of course, if it's realeased under a new as-of-yet unnamed publisher, then next fall or later is fine with me!!
