I have two big problems.
1. I always plan weeks in advance what kind of "expensive item" I'm going to purchase next. I hate it. I already know that my money for October will turn into a Dries van Noten bag and some Burberry scarf. I don't include basic stuff from Zara, COS etc in my "calculations". I really want to stop buying expensive stuff, I'm a 19yo student, I actually can't afford a bag for 1000€.
2. I often do not ever wear the stuff I buy...
