I'm in the process of writing a novel. I mostly write straight through in a linear manner, sometimes edit. But I wondered if it's okay to write very short chapters, most of my chapters are 1 + 1/3 A4 pages. I like to write chapters in short and focus on one particular happening and then write another chapter. I do not want to stretch my brain and put in 'filler material' though. Is it okay if my chapters are short?
