Believe it or not, this is my dining room table. We eat on the couch.
The large, blue coffee mug on the left of my laptop is my Stitch (as in Lilo and Stitch) mug that I drink out of every day. The dog is Scudder, my male black Lab.
The mess...well, don't my floors look great!?! *LOL*
Between hectic editing and writing schedules, arthritis, and really sore bodies, hubby and I haven't gotten the rest of the flooring done in our bedroom or our office. My laptop will still be in the "great room" (we don't have a separate living and dining room, they're one large room) but most of that mess will be on my desk...in the office. *LOL*
I like the view. That window looks south, on our backyard, overlooking a freshwater canal. We get birds and squirrels and I enjoy looking at the view, such as it is. It works for me.
If you need a neat desk, by all means, use one. But you can write anywhere. Don't use not having a "perfect" space to write as an excuse to not write. Whether it's at a table, a desk, a couch, your bed, or a McD's or park bench, WRITE.
