Creative writing isn't what you think it is. It's not sitting down in a cafe and writing the entire outline for your book series on cocktail napkins. If you have that kind of time (and probably a medium-point pen at best) then, by all means, proceed onward. Writing can easily be broken down into smaller, basic parts to the point that even busy people are still able to make time to write if they're truly motivated. There isn't any big secret. It's just something we simply don't think to do. It's called flash writing and it still counts in terms of self-satisfaction and having actually written something for the day.
Remember in school when you used to have homework? Or, better yet, you know how they say to get up from your desk for at least two minutes every hour? It's sort of like that. But, instead of employing the foil method to expand algebraic expressions over and over, or circulating your blood to relieve lethargy, you're exercising your creativity.
Creativity is not limited to fiction writers. Even non-fiction writers need to capture those exacting details to describe their ideas. So how do you practice your creativity with a full schedule? Create at least two minute intervals (every hour if you can) during a certain block of time each day for flash writing. When the timer dings, simply jot down a quick description of whatever comes to mind or choose from a premeditated list.
You do not need an entire story. You do not need a whole slew of characters. You can, however, get as detailed as your schedule and your mind allow. You can also use programs like ZenWriter or OmmWriter Dana to help you relax into your writing exercises for the day. Also, consider keeping track of your flash writing exercises in a basic list. Who knows, maybe some of them will be worth further development.
To start you off, here is a short list of intentionally vague writing prompts to use as you so choose.
- Describe a character in ways that would make anyone hate him/her/it.
- Describe the room around you as though you've never seen it before.
- Describe your last meal as though it were your last meal - use as many metaphors/similes as possible.
- Create an emotional atmosphere (fear, excitement, boredom) by describing a house or neighborhood.
- Describe a character who is (jogging/rock climbing/swimming) for the first time.
- Describe a character who realizes that she/he/it is in love without saying "love."
