The morning pages consist of three pages written stream-of-consciousness style first thing in the morning. There is no wrong way to write the morning pages. You simply write whatever crosses your mind without stopping. These pages are meant only for your eyes, so it is important to shut out your "inner editor" and write explicitly what's going through your mind. If you can't think of anything to write, just write "can't think" over and over until a thought comes to mind.
Creative writers use writing prompts to inspire creativity and imagination in their writing. These kinds of prompts can be found online or in writing programs, and are usually either composed of single words, phrases or situations. For instance, "Create a new human-esque race and describe it as thoroughly as possible. Be sure to describe appearance, culture, values, beliefs, etc."
The jumble story is a random story created by a raffle system. The idea is to choose four numbers between 1 and 10 from four piles of numbered tickets. Each pile consists respectively of characters, settings, time periods and situations that you or another party created. Once you pick from all four piles, create a story using the character, setting, time period and situation. This method is effective for getting you to think outside of your comfort zone and just write.
Create a character whose journal you will be writing in over the next few weeks. Write journal entries as if you were this character who has a secret she is afraid to confess. Explore options of the character as she ponders the secret and reasons why or why not to tell it. Discuss her feelings as she goes day by day with this burdening secret. Keep the character consistent. For instance, if you write in one entry that she has a nut allergy, don't make the mistake of writing that she ate from a bowl of bar nuts a few days later.
