"Go out there and talk to women" does not mean "start hitting on complete strangers". It means learn to interact with other people, including women, on a real human level, first of all. Of course you're gonna get shot down if you just try to pick up random women.

And before you say "blah blah attractive guy not get rejected wah unfair women so shallow": if you believe conventionally attractive men can just waltz in and pick out any woman they want but you don't have that advantage, why would you try to do that instead of maximizing the address assets you do have—for example, at the very least, the ability to learn conversational skills and actively improve your personality? You are not doomed. You just find it easier to say you are, or to make the most half-assed of all efforts (hitting on some random stranger and then complaining on Reddit when it doesn't work out), than to take responsibility for what you CAN change.
