Let's write!

Think about the past couple of days and choose something that you did or happened to you. It should be something that lasted no more than a minute -- it can either be some short event, like a phone call or wrong number, or a small part of a longer event, such as locking the front door, getting in the car, and starting it up to get to your destination.

Now, write that thing as if it happened to your chosen character. Translate the event to whatever the character's situation is (for example, if it was Luke Skywalker, "getting in the car and starting it up" might be "climbing into the X-Wing and starting the launch sequence).
