If I'm at work or out driving or outside with nothing to do, the ideas just come to me and I get the motivation to come home and write, write, write! But since I only have one desk that also holds my computer, I sit down to write and instead f5 my friends page on LiveJournal.
Bay's post reminded me of a part of writing that I hate: description. I can get the narration down. I can handle setting. I just can't do physical description of the character, especially human ones. It always seems so forced to me, and unless the part of the physical description is important to the character, I skip that too.
