I'm behind my laptop most of the time, working (or playing around on Twitter). I usually find a way to work on it even when I'm eating dinner. And when I do put it down, I'll pick up something else. I've got a box of crafts projects just waiting for attention. I'm not idle very often...and sometimes, I have to force myself to do nothing. The importance of daydreaming just can't be neglected if you're a writer.
It's easy for an author to keep their minds busy, even if you don't have your face shoved into a laptop screen. I think about plots, imagine conversations, endlessly go through my list of stuff to do...think about all the junk I'd like to buy on Amazon, and pine for Game of Thrones (hangin' in there until March).
None of it leaves a lot of room for daydreaming, but it's important to make a point of stopping your brain every once in a while. Put down the smartphone, walk away from the TV, refuse to look at your laptop and just be still for a moment. It's in the quiet spaces that daydreams are born, and daydreaming is an important activity for any writer.
The good ideas creep in once your mind is free to daydream and wander, roam and ponder. Great ideas rush in to fill those quiet moments, when your guard is down and your mind isn't so busy. Authors need to daydream to get the creative juices flowing, and to stay open to new ideas. Fresh thoughts create new stories. So close the laptop and put your feet up on the desk.
If anyone asks why your eyes are closed, tell them you're working on the next great American novel!
