I don't know about where you are, but it's still pretty cold here in New York. That being said, with Daylight Saving time, I FEEL spring is here.
I also noticed that I go through a writing change per season. Winter and summer are my least productive seasons. In summer I'm out a lot, and in winter I'm moping because I can't be out a lot (though I do love a good snowstorm.)
Fall is a perfect writing time for me, since I hate that time of year with a fiery passion (I know I'm probably the only person on earth, judging by all the fall-lovers in my Twitter/Facebook newsfeeds.) But I really do dislike the season. To me, early fall is the most depressing, since all it signifies to me is summer's end. I was brought up on this belief, after all:
But then spring comes and it's a whole new story. I have these bursts of energy to create, and renewed hope for my works' success. Maybe it's because of the all extra sunshine.
Or maybe it's just the way I roll.
What season are you most productive in?? Or is it just easier for you to write in a specific season???
