To reiterate:
1. Be Confident, not arrogant. If she turns you down, smile, say "Thanks anyway", and go on about your business.
2. Establish a friendship first. Be friendly. Smile. Listen attentively.
3. Ice-breakers are deal-breakers. A simple "Hello" may be all that is needed.
4. Share the conversation. Don't interrupt, and don't monopolize.
5. Manners, manners, manners. Look at her eyes. Don't stare at her breasts. Offer to pay off her bar tab. Ask her to join you (and your friends, if you're with a group).
6. Be inclusive. Let her know that you are inviting her into your social circle, as well as into your life.
7. Be ready to "cut and run" if she shows any reluctance toward getting to know you. Smile, say "thanks anyway", wish her a good evening, and walk away.
8. Practice good personal hygiene. Bathe, brush, and floss. Get a nice haircut. Use no more than a teaspoon of cologne over your entire body. Use scentless deodorant.
9. Mind your appearance. Keep a healthy weight for your age and height. Dress like you're going to a job interview. Stand and sit up straight. Smile.
10. Avoid girls that already have boyfriends or a circle of admirers. Look for girls that are with other girls and introduce yourself to all of them.
11. Go places where there might be compatible girls, and where you can meet the same people regularly over extended periods of time (there's no better way to say this). You can't expect to find girls that share your interests in places that you don't like to go.
12. Don't act desperate. Dating is a waiting game. They will figure out that you're available on their own.
13. Take risks. Seek contact with girls you've never seen before, and with girls you might not immediately jump into bed with.
14. Never express anger or contempt toward the girl's friends, interests, employment, or behavior. If any of these is a turn-off for you, smile, say "thanks anyway" and walk off.
This should do for a start.
