take any picture you have at home, in your computer, from the net or in a magazine and get going.
Write the story of this picture.
Invent a story around it.
What happened before and after? Why was this picture taken? Who took this picture? Where was it? Add your senses : touch, smell...
Go grazy with the plot - write a story that you like!
And if your story is boring - that is okay too!
Another extra idea : Change pen colour for every word you write so that you slow down your pace and for the way it looks!
Here a few to inspire you if you don't have any close by.
