I remember when I started trying approaches long ago in the faculty. I only limited myself to saying hello to the women with whom I had eye contact. Sometimes it happened that at another time I could talk to some of them. Even one of them invited me to a party with her friends (but at the party I could not achieve much)
On the other hand, I never had luck in the street. It seems that I can only approach them when they are stopped, never when they are moving.

you can always switch between direct mode and not-so-direct mode.About to make a guess,hope you can hit . But good for you men.Not everyone goes to talk to somenone,just imagine how it could have been.
Good luck
