Everyone procrastinates. No one wants to write that essay, or clean the bathroom. If it’s not food, sex or sleep, your body is just not interested. Sure, in the long run you might need to write that essay, to get that degree, to get that job, to earn money to buy food to survive. But your body doesn’t understand, or care, about that. Your body is a thing made in simpler times. It is built for when survival entailed going off to pick some plants to eat, some reproducing and maybe a bit of sleep afterwards. But modern, western lifestyles are a horrible mismatch for this way of living. Imagine giving a caveman a long, boring, task to do such as moving numbers from one column to another (maybe with sticks, it could take a while to explain the concept of computers). Why should he do it? He gets no food from it. He gets no joy from it. Doing this task does not make him any more attractive to cavewomen who might then want to have his babies. It takes a reasonable amount of energy that is better spent in other labours. So why should he do it? To him, the answer is he shouldn’t. And this is the thought process your brain goes through when faced with a task. While the conscious parts of your brain know the real reason for the task, your ancient parts of the brain, which we share with our ancestors and other animals, do not.
Think about it. How do you procrastinate? Making a snack? (means you won’t starve to death) Taking a nap? (means you won’t be too tired to see the tiger of death headed your way) Talking to friends? (maintaining social bonds which one day might lead to you making tiny replicas of yourself vis someone else’s genitals) Watching cat videos? (evolution can’t explain the internet, but taking joy from something which takes away no resources you may have gained from the other tasks means your body agrees to it).
Cleaning your own room is therapeutic and has actually been shown to improve your mood while doing it and afterwards when you’re in your nice clean room. But when it comes to the gross shared bathroom every uni student has encountered, you put it off for longer. You procrastinate away from it. This is because you gain no real benefit from it. It’s not dirty enough to give you diseases (yet), and you don’t spend enough time in it for it to benefit your mental health. If you can’t see an immediate advantage, you won’t do it.
Procrastination is all about cost and benefit and finding the balance between the two. If the immediate payout does not equal or outweigh the energy expenditure required to perform the task, then the inclination to do it will disappear.
Think about this the next time you put something off and do something else instead. Would what you are putting off benefit a caveman? Would he benefit by doing what you are doing now? But don’t listen to your inner caveman. Listen to your inner modern human who wants that essay done, because they know that you really need to do it. Don’t let them in only at the last second to write it. Go and do something productive! Go!
