Step 1: Find a good spot. Look for places with comfy benches or a tolerable ambient noise level.
Read the rules for a comprehensive list of do's and don'ts.
Step 2: Assume the position. Sit or lie down, depending on your personal preference.
Step 3: Engage in light activities only. No loud talking, no intense eye contact, and no unsolicited opinions about the meaning of life.
Step 4: Maintain a low profile. Keep your eyes closed, and your hands still. No fidgeting, no reading, and no attempting to start a conversation with someone who's not you.
And that's it! With these simple steps, you'll be a napping in public pro, just like Steve.
