Be yourself, who's nice, respectful, humorous, and genuine.

A man should be Confident and not try too hard to be impressive.

All the good advice has been given, I can only add BE WELL MANNERED!!!

as a happily unmarried thirty sumthin woman, all i can say is be honest. dont try to act like "that guy"......we all know a friend who fills the shoes of "that guy".  just have common respect in how u address women........woman vs. broad or chic, i find it is really the smallest ,and simplest of things,like noticing her different hairdo, or perhaps the softness of her skin,the sweet taste of her lips,etc etc etc that have always made the biggest and fondest impressions........just be a nice,honest guy that doesnt hav pik up lines,and believe me,u will impress.

They are the fairer of the sexes, and should be treated delicately and with respect. Chivalry is not dead, I still open and close doors for my old lady and she loves it. An unexpected flower delivery to her job will put you in quite a favorable lite. Always a toe curling experience. 

How big is your wallet??  I think wallet size and female impressing goes hand in hand..

However, should you want to impress a 'good girl' use the suggestions from the others.. :)

Say this and she will be eating out of the palm of your hand..... Gorgeous, intelligent, kind, sweet, charming, witty, hilarious, friendly...well enough about ME! How are you?
