8. Letting yourself fall apart.
We've all seen it: it's about 11:58pm on a Tuesday night and there's a cute woman crying her eyes out at the bar to an innocent bystander. Or maybe it's an adorable guy shelling peanuts vehemently at the end of an empty bar, going on and on while the bartender tries to find an out. Don't be that person. Your heart is big and it's full and there are many, many stories tucked inside. Do yourself (and all of us) a favor: keep them there. They're your stories. Two vodka tonics, a first date with a semi-decent dude or 50-cent wing night at your favorite locale aren't open invitations to let the flood gates open.
9. Letting just anyone in.
There comes a point when loneliness will invite itself into your apartment in the middle of the night. Let it. There'll come a time where it's in all of our lives. Just because you're lonely doesn't mean you should invite your one-night stand to your best friend's wedding, or the guy you just started dating to the holiday party where everyone else is bringing a plus one. Don't be afraid of going it alone. In fact, fly solo and own it! Desperation doesn't look good on anybody, sista.
