1) be confident
2) be genuinely yourself
3) smile and spark an interesting conversation then transition
to conveying your traits/experiences to her.
4) try to get her to share something about herself. she will
most likely reciprocate.
5) look into her eyes
6) look at her beyond her looks and look for characteristics
that you like about her
7) compliment her
Girls feel much more comfortable and better when we are
complimented about our interior selves, that we are liked for being
who we are not about how we look. What I rarely find is a man that
can bring out the real selves about them. Be willing to make a fool
of yourself and DO NOT use lines and you'll be fine. To me, humour
is attractive! 
looks like one of those tips from dating websites.. some are gd,
but don't just follow wholesale blindly, some steps are too
"over"
eg. (5), (6), (7) >> shldn't try those, esp a newbie like
u
but dun worry, having a mutual fren will make things much
easier
essentially, it's all abt breaking that ice:
(1)try to get some eye contact with her, if she notices you just
smile at her ... don't rush, yr aim is to make yrself a
familiar face to her
(2)when she has noticed u enough to return u a smile(most likely
after a few times of u taking note of her), only then can
u approach her, and be confident!!
(3)tis the time to start yr convo >> "going for yr
class??", "u know so and so??" type of opener, casual w/o sounding
too despo
openers like "u free to chat" will most likely scare her off, so
don't use it
***once u hav broken the ice, it'll be much easier for u to
start convo nxt time, strongly advise u not to get her no yet,
1st meeting too abrupt
