Huh, didn't think deleting an entire sentence to fix one typo would be so common. Maybe it's not so weird after all.
While I don't perform my writing sessions in segments like Lua and Suuper, I do often take frequent breaks when I'm writing. Usually when I reach a point in a scene that I feel sort of stuck on, I would get up and starting walking around the house to sort of clear my mind. This can go on for about a hour straight, and when I'm done I return to my station to write more, only to of course, take another break. Funny enough, it's not always when I feel stuck on something. Sometimes I just stop to take a break just because.
Another note, I hate writing in hot temperatures. I can sometimes ignore the heat, but often times I find myself feeling drained when I try to push through it.
