My most productive writing time used to be in the morning. I would sit down, all fired up, and words would flow from my mind to my fingers to the keyboard (or page, if I was hand writing.). Yeah right, I know this is every writer's dream, but it occasionally did happen. And it used to happen more in the morning than any other time.
Not so, these days.
Of late, I find I spend my mornings checking email, reading my blog roll, checking sales on Kindle and Nook and Smashwords. I log these, play a few games of solitaire or whatever, have a mid-morning break of Greek yogurt, and THEN I start work. And though I work until lunch, it isn't until after lunch that I really get going.
I'm not sure why this has changed. But that's the way it is now. I still have the best job in the world.
