While I'm sure there are plenty of you out there that have absolutely no problem meeting new people, the rest of us can sometimes feel like there aren't any fish in the sea. [1] Even if you're out and about all the time, it can be easy to fall into the habit of just socializing with your close-knit group of friends instead of branching out and stepping out of your comfort zone. Sometimes the most basic ways to meet new people are the ones that we forget the fastest. To get a reminder course in meeting people before the weekend,

• Once you're out, start looking around you. Keep your eyes open for guys that are checking you out. Sometimes we miss the people who are showing us interest — making eye contact, glancing in our direction, or throwing us a quick smile — because we forget to be aware.
• As scary as it can be to take the initiative, you may be surprised how effective introducing yourself can be. When people are out socializing, it usually means they're looking to talk. All it takes is one introduction to get a conversation going.
• Learn to follow your instincts. If someone seems really kind, and you get the vibe that they're a decent person, consider giving out your phone number — you never know what the outcome could be.
• By all means, once you've started a conversation, keep your attention focused on the person. There's nothing more frustrating than talking to someone who's eyes are anywhere but on your face. Remember to pay attention — listening gives you more topics of conversation and you'll avoid awkward lulls.
