Are you able to write in short spurts? Or do you need at least an hour (maybe two) to get in the zone of writing?
I found I need a good hour to get into that Zen-like state where I tune everything out around me and just concentrate on my thoughts and fingers to the keyboard. Now, this really only applies to writing a story. I am writing this LAST! A to Z Challenge Blog to the "Coldplay 2011 Glastonbury Concert" blaring in the background on TV.
When I first wrote, which was around 2004 or '05 and it was Harry Potter FanFic, I would get so into a zone, I'd forget to eat a meal and not be very hungry. I noticed I lost a bit of weight, which was fine as I needed to but that's not the case anymore. I don't think I could sit and concentrate so long now, ten years later.
People talk about going to a hotel room to write for a night or two without interruptions. I have a friend who'd love a cabin on a lake out in Western Maryland. I'd love to do a retreat with a few writing friends rent a house somewhere in the mountains and write most of the day, then go out to eat! Now, I'm happy with quiet and no one demanding anything of me. But, I'd take a free hotel room where I could order room service, sit and type my little heart out.
