You have to clean your apartment
Yeah, guys, sorry. You can always blame your dirty-ass apartment on your roommates or laundry day when it's first viewed by virgin eyes… but when someone sees the same discarded box in the same spot two weeks in a row, that's when the judgment begins.
So, clean your apartment and try to pass the illusion that you don't live like a complete vagrant. In fact, regularly cleaning your apartment will only lead to a nice lifestyle, despite what most college-aged people and young adults assume.
To sum it up: stop sweating that first date -- they come and go, and you'll acquit yourself better if you're super relaxed anyway. The "I better not screw this up," high-stakes action doesn't kick in until the second date, anyway.
