Saved up some money and got some nice clothes from H&M. I recommend H&M because they have really nice clothes for good prices. It's been a while since I got new clothes so this changed my style by a lot.

What did I observe? In the university cafeteria, as I'm putting back my tray, I notice some girls (pretty good looking) looking at me. Then, another girl (I've seen her before but we don't really talk) says hello. It was a good day.

TL;DR : Dress nice guys. It helps to a certain extent.
