Well, what i would like to know is the best way to approach a woman that you find attractive. Anyone can help me out?

Details!
Women love details. If you practice, you can accurately pinpoint things that matter to her... This should not be confused with complimenting a woman. If you can remember details about, the first time you saw her or met or whatever, it is a surefire way of getting to talk to her and letting her know she made an impression on you.

Questions!
Most Women love to talk. If you ask intelligent questions, she'll be happy to answer... more so if the questions are about her. NOTE: don't be creepy and ask personal or intimate questions off the bat. It's crucial that you keep your head straight... as in listen carefully, there are important details in the answers she gives you. Some guys get completely in "awe", they can't believe the woman is actually talking to them. Stay focused! and ask more relevant questions and remember her answers.

Good luck!
