just be you
if that aint enough
she aint worth it
most relationships that go bad are cuased by FAKE ass persona
you put on some front
and later they get to know the real you and say
what a asshole.,,

as far as impressing a chick
be attentive and nice but not some suck up ,hard up type
listen to her,get to know what she likes and DOES NOT like even more important

good luck and aint love a wild ride
peace
