Summarize this article in one sentence.
If you are looking to pick to girls, it helps to be mentally and physically prepared to do so. Before you go out, have a few funny anecdotes lined up, should the opportunity to talk to a girl arise. Continually scan your environment for suitable candidates; you never know when a hottie is going to wander by. Pay attention to your surroundings so that when an opportunity arises for small talk, you can quickly think up an icebreaker comment about something nearby. If you are a slacker dressed in a business suit, the disconnect between your personality and your clothing is going to come across very quickly in conversation and confuse the girl, or make her uncomfortable. Dress in a way that advertises the kind of person you are, but do choose the nicest clothes of your preferred type that you have available. At very least, make sure that your clothing and hair are clean and presentable. If you've got a few extra bucks to spend, invest in a new pair of shoes. If you want to pick up girls, you need to go to where they are. Choose a place with a lot of foot traffic to hang out, such as a street with many restaurants, the sidewalk outside of a popular coffee shop, or the arcade in front of a big bookstore. Also, plan your search for a time of day when the girls who walk by are likely to have a bit of time to spare. People who are rushing to get to work or or an early class are unlikely to be in the mood to stop and chat. Aim for the lunch hour, or mid-morning, when many people go out for a coffee break. Most women will be put off by a man (or woman) slouching on a street corner, calling out to various girls as they walk by. No one enjoys being harassed in the street! Your advance will seem far less threatening and contrived if it appears you are busy or out running errands. Even though you may actually just be walking around aimlessly looking for girls, it's best to have some kind of destination in mind, in case an opportunity for conversation or an invitation arises ("I was just on my way to the Farmer's market, would you care to join me?") You can also try "getting lost" in the vicinity of a known destination, so you can ask a girl for directions. ("I was just looking for the Apple store, but seem to be turned around. Can you help me out?")
Always be prepared to meet a new girl. Dress neatly, in a fashion that reflects your personality. Figure out where the girls are. Look like you have a purpose, besides picking up girls.
