Morning Writing Exercise

I've started myself a new habit.  Not a bad habit, but a good one.  Every morning, I get up 25 minutes early and write to a prompt for twenty minutes.  I hope to achieve two things in doing so.  One, I can get my brain firing early on in my day.  Two, I get more practice in writing.  My first three days I've been using prompts that I made up myself, but later on I may use prompts from Writing Excuses or any prompts that anyone would like to give me.  My flash fiction posts may or may not be one of my morning writing exercises.  My latest flash fic, Guard Weasel, was my first morning exercise.
