Here are a few techniques for achieving optimal procrastination:
Identify a task that you can do for an extended period of time without getting bored, but not too long that you'll get anxious. This is your sweet spot. Spend all your time in this sweet spot, and you'll be a master procrastinator.
Take an hour to think about what you need to do, but only after you've already started doing it. This will ensure you're doing something, but not really accomplishing anything.
Don't plan your day, week, or month. Let life surprise you with its endless possibilities. This will keep you on your toes, and your to-do list will be a never-ending adventure.
Plan your day for tomorrow, but only after you've already done it. This will ensure you're always on schedule, but never really getting anything done.
