1. That this Tinder guy is not worth meeting. Every time I've felt like, "Well, he's kind of boring, but he's not a total jerk and he seems sort of hot," and went on the date anyway, I just found out in person that he was exactly who I thought he was (and if anything, even worse). Even if he's perfectly nice, if you're not really psyched to meet him, it's a waste of time for both of you. Skip.
2. Feeling like you shouldn't get off the taxi because something feels sketchy. Sometimes I've waited to get off the taxi for a few blocks because it seemed crazy dark, and I always think it's better to walk farther home than to get out sooner and wish I had stayed on that train because this part of town looks like an episode of American Horror Story.
3. When you're with a guy and suddenly start feeling uncomfortable for any reason. Even if he didn't specifically tell you, "Oh, hello, I have a knife and want to use it for murdering purposes," if you have a feeling that something about him seems like he could be one of the killers on Scream Queens, just tell him you're really tired and need to head home. This is 100 percent better than waiting to see if your suspicions are correct and then having something shady happen.
4. That your friend is not OK even though she keeps saying she is. You know your friends really well, so accepting their "No, I'm doing fine, really!" answers when you know they seem like they're having a hard time isn't helpful for either of you. It's best to bring cupcakes by unexpectedly just in case. Even if she's fine, cupcakes are life.
5. That you didn't bring your keys. Shake your purse to make sure. Just do it. Locksmiths are not cheap.
6. Not feeling sure if you should grab a condom or not. The answer to whether or not your gut is right on this one is always yes. Your gut is very wise.
7. Wanting to buy that Forever 21 dress but hesitating because you're not totally sure for some reason. I have a rule I stick to pretty religiously and that is: If I try something on and go, "Oh, hell yes," then I buy it. If that doesn't happen, I don't. Whenever I break this rule, I always just end up with some dumb, weird shirt that fits like crap and lives on my closet floor.
8. That your designated driver had more than one drink. Even if you're wrong, this is not the kind of thing where you want to be like, "Eh, screw it. I'm sure it's fine," and then show up on the nightly news later on because your car looks like it was in an action movie. Grab a cab.
9. That even though the guy you're dating is great, he's still not The Person, and it's OK to just end it. Plus, in my experience those relationships always get to a point where you finally start having major problems (like suddenly picking fights with them because you don't like them and it's making you so freaking mad because you just want them to be The One already!) and then decide to end it, so just skip the inevitable drama and save both of you some time.
10. That something isn't right about that new job you got offered. "If something seems too good to be true it probably is" also goes for six-figure jobs that let you work from home for only three hours a day and do not have an office anywhere or a website that's currently functioning. Keep looking for something that is not a likely pyramid scheme.
11. When you think about breaking up with a guy, but then he does something sweet and you're like, "Maybe not?" OK, so he brought over your favorite cookies from that fancy place uptown that you usually only go to once a month after you get paid. Do you really want another month of him not responding to most of your texts, but then sometimes bringing you cookies you could totally buy yourself? No.
12. When you've been partying a lot and your body is like, "I need a night off." Just stay in tonight, okay?
13. That you didn't turn off the oven/turn off your hair straightener/blow out the scented candle/something else that will probably burn your house down in a giant explosion. It takes two seconds to check those things and possibly a whole year to find a new non-burnt apartment and replace all your stuff. Worth it.
