I feel like there are 3 aspects to procrastination: distraction, anxiety, and flow. Also there is a disconnect between what you know you must do and what you wish to do, between the logical “rational” you and the emotional you. From my understanding of the structure and function of brains your cerebrum allows for higher thought, is what determines what you know you must do on an abstract level, and is the newest part of our brains evolutionarily. The limbic system is a different part of your brain, older evolutionarily, and responsible for your base desires like hunger and sexual arousal. The limbic system comes before the cerebrum because it matters more. You don’t need higher thought to survive. You don’t need homework to survive. And when you’re sleep deprived and stressed out I’m pretty sure your cerebrum functions worse. It starts shutting down before your limbic system because it’s less important to your survival on a basic level. Point is you a basic bitch.
