Shopping is a bit weird with me. Sometimes I buy less (for example, luggage with an airline ticket for a short stay, when I buy less, then I pack the necessary wardrobe in a minimalist way), sometimes more (when friends come to hang out at home), while for my daily needs I buy just as much as I need.
My purchase plan depends on how long a period I plan for. The longer the period, the bigger the reserve I plan. So, for example, when we moved into the apartment, I built a built-in closet, which we thought was too big and that we will never fill it, while today we know that it is too small😀
