Have you heard of morning pages? I can't recall where I first saw them mentioned, though in researching (to give credit where credit is due) I find it's an idea which was popularized via Julia Cameron's "The Artist's Way," a book which I admit I have not read and on which I cannot offer an opinion.
In any case, the concept is simple: first thing in the morning, as soon as you roll out of bed, before your brain has had the chance to fully wake and get its house in order, you sit down and write three full pages. Longhand. That's right: just you and a notepad and a pen or pencil.
What do you write about? Whatever pops into your head. Write about the crazy dream you just escaped. Write about your plans or worries for the day. Write about what you're going to eat for breakfast. Write about how weird the word "morning" looks to you right now, for some reason. Write about the sound of the rain and how it reminds you of sleeping in the back bedroom at your grandmother's house that July between sixth and seventh grade, when birds created a nest under the eaves and one memorable afternoon, a fledgling flew in though the window and about gave Grandma's fat old tabby cat a heart attack.
There are no rules. Just fill those three pages.
As you'd kind of expect, much of what I write is dreadfully dull or complete nonsense. However, in giving myself the freedom to explore whatever comes to mind, I've also found the seeds of short stories or poems or blog posts, wrestled with life decisions, and sorted out tangled scenes in larger works-in-progress. It's also a good way to work on writing discipline: simply sitting down at a given time each day, knowing you have to write something, no matter how sleepy and uninspired you may feel.
In a perfect world, I think I would always start my days with morning pages, and end them with writing down my "Three Good Things." In practice, I manage stints of three or four days at a time, but have never really gotten consistent about it. And I should.
Have you ever tried morning pages? If so, how have they worked for you?
