MAN UP.
Say, hi, hello, hows it goin?..."I really like your book bag"..."wow, those are really great shoes"...ummm...how about, you have the most beautiful eyes?
How about, "hey, how you doin...my name is John smith, what's yours?" What's your major? Wow, I really like your smile! The list goes on, etc, etc, etc. Use your brain. Woman are looking for smart, intelligent, witty, secure men. Kinda the same way you are looking for a smart, intelligent, witty, smart woman. Rate yourself on those categories, then find a woman that is similar.
Up your dating IQ. What kind of clothes are you wearing? How's your shoes? Do you wear a watch or cologne? When you picture what the woman you want is wearing, does your wardrobe match this, or is it time to get a little more stylish? Hows your hair? How about your teeth? If you need improvement, do it. Just like you, woman notice appearance first and foremost. You can overcome some of this with a great personality, but I recommend polishing up a bit first. It can only help.
Ok, keep in mind that woman are actually versions of human beings as well...lol. They all want love just like men, they are all a bit insecure at least at some level. They want to be talked to and they also want friends as well. Since you are obviously a novice, just go with the friends kinda hello first. Girls are tricky, they aren't just going to jump up and be your girlfiend because you said hello. Keep in mind to that if you are dealing with an attractive gal, that means there are 500 other "bucks" out there trying to land her as well. Competition is fierce. Are you the big buck on the hill? If you somehow match up with this gal in personality and chemistry, you may just be the most dominant buck on the hill.
Now, here's some tricks. Big smile...smile a lot. How about being funny and humorous? An average looking guy with big smile and sense of humor can get well above average looking women...and way above average personality (personality is really the most important thing down the line) If you can get looks and personalilty, you're all set...tough to do, but very possible.
Also, practice by just talking to random everyday gals. Even the ones that arne't super attractive can have super personalites and be fun to be around. Engaging a gal for her personality rather than her looks generally leads to successful relationships. I believe the expression is "friends first".
