Step 1: Find a valid excuse for why you're leaving early.
Step 2: Grab a granola bar and a thermos of coffee (you'll need it for the long, hard journey ahead).
Step 3: Make a break for the nearest park or coffee shop. The open space and caffeine will help clear your head and give you the focus you need to plot your escape.
Step 4: Plot your escape route. Use a map or a GPS to find the shortest route to the nearest highway. Once you're on the highway, you can make a dash for it!
Step 5: Make your move! Leave the cubicle behind and hit the road!
