A closer look
Unfinished tasks stick in your memory significantly longer and with far more intensity than tasks you have actually managed to complete. Bluma Zeigarnik discovered this in the 1920s after noticing waiters could remember incredibly complex orders perfectly until the bill was paid, at which point the information vanished completely. Your brain acts as a relentless, nagging manager, holding onto every single incomplete chore and unwritten email just to torture you while you are trying to fall asleep. It means that the only reward you get for actually being productive and finishing your work is the sweet, immediate amnesia that allows you to completely forget you ever did anything valuable in the first place
