The more you do something the easier it becomes,
Why would you not talk to them?
the worst they can do is fob you off or ignore you, And so what?
Women love direct men,
I used to be like that but one day forced myself to talk to a random women on the train which led to 2 fantastic years with her
After i talked to that girl it became kind of a rush to approach them
As for the confidence thing, try a couple things for the next few days, hold your head high and look people in the eye when you talk and see what happens, people and females treat you soooo much differently, how can any one respect you if you cant even look them in the eye?
and some women don't mind a guy who's lacking in confidence. Someone who comes across as being overly confident can just look like they're just wanting sex. If that's what both parties want then it's not a problem of course, but if you're out there wanting a relationship then being shy doesn't necessarily hurt. In fact some women quite like the whole shy thing
