Procrastination and its delights — Episode 2: The three types of procrastinators

1. Arousal — thrill seekers who say they need the adrenaline rush from waiting till the last minute

2. Avoidance — put off hard or boring tasks to avoid being seen as failures; then they can say they didn't have enough time instead of not having the ability

3. Decisional — chronically indecisive in every aspect of their lives
