I'm in the middle of reading Overwhelmed, by Brigid Schulte. In chapter 7 she brings up an interesting fact that I thought I'd ask about here. Typically, a physical labor job runs 8 hours a day, and the the worker is pretty well cooked. After that, mistakes go up and you lose productivity. In mental labor jobs, the average worker only has about 6 good hours in him, and after that, he's messing up, too. These are research generated results according to the book.
Here's my question: on average, how many hours can you write before you start feeling drained? Is there a difference between writing and editing? Can you edit for a longer or shorter period of time before you are mentally fatigued? On average, mind! I've had nights when I just couldn't shut it down--the story was there, and it had to be written. I've even been able to get on a roll editing at times, and sometimes I might stare at a screen for an hour, dink with one sentence, then give it up and come back to it at a later time. I've had days that I couldn't write because I was so physically tired I couldn't compose a sentence orally, let alone write it down. Those are rare days, however.
In my own experience, I've found that I am able to write steadily for about an hour, take a break for tea, then come back and hit it another hour. After that, I need to do something else for a while. I need to read, or draw, or go for a walk. I can come back later in the day and do another two hours. Again, I usually require a break after an hour. If I'm physically tired or distracted, I need to get up and move about every thirty minutes instead of every hour. I've noticed that I need fewer breaks when I'm editing, but I've not been editing long enough to have a good average yet.
So what about you? How long, on average, can you work at your creative effort before you hit the point of diminishing returns? I ask, because this discussion about productivity has come up in a couple of places with creative people I know and like. So, if you don't mind being part of my very unscientific study, I'd like to know your thoughts on the working day for a writer, and what your ideal day would be? How long would you spend writing? How long editing? Where would you take your breaks? How would you spend them? What breaks are most effective for improving focus and promoting a relaxed, creative mind environment?
