How to prevent myself from buying things I don't want
I use cash exclusively. I go to the cash machine once a week and withdraw the money I want to spend in one week (so I have to plan if I want to buy something expensive). Otherwise I leave the card at home. As bonus you get anonymity, i.e. big brother cannot track you.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
