Be courteous at all times and be polite to her friends
, colleagues and family. Always offer to help when she is struggling with something but not otherwise. Too much pandering is a turn off for most modern women. Most modern women are proud of the fact that they are independent and have their own career or income. Respect this fact and show them you are there if they need you but that you know they are more than capable of looking after themselves. If you can master these simple things, you can easily impress a girl and win her heart.
