Step Four: Check your email.

You may have missed something while you were out preparing to be a writer. Who knows -- maybe Groupon is offering 50% off on a literary agent's commission. 

Step Five: Become aware of your surroundings.

You'll want to pay careful attention to any noises in and around your work area. In particular, keep your ears open for clicks or hums and spend the required time first investigating the sound and then abolishing it by turning something off or going back out to the store to buy earplugs. It will no doubt be a different store, more than a mile away.
