approach of girls

best example is me. i'm not so smart to explain. but i liked a girl very much. one day on my B'day i went n gave a chocolate to her. She scolded me well. i'm really upset. but she called me and said i should never talk to her. the action is reversed. she talks only to me.. U try dude

well i guess you should know what's her weakness and do some of the things that would impress her

You can't be smart in appearance. Maybe look smart but that's not a good idea if you want long relationships with people around you.
I think you meant that you don't have great physical features but you have a good character. Well that and confidence is what it takes to attract girls. You won't be getting all the Hollywood babes, but you should know that women aren't attracted only by big muscles and perfect hair.
