Warning: The following techniques are not for the faint of heart (or those with functioning productivity skills). Proceed with caution and a fully charged snack supply.
Stare at the wall for exactly 47 minutes and 13 seconds. Record the time. Repeat. Repeat. Repeat.
Watch 12 consecutive episodes of your favorite show in one sitting. No, really, just 12. Don't worry about plot holes or character development.
Open 17 tabs in your browser and stare at them for exactly 4 hours. Don't blink. Blinking is cheating.
Remember: Procrastination is a skill, not a crime. (Just don't tell your boss.)
