The realist in me says "You can't control another person's desires". They have to be interested in you atleast a little bit before you'd have a chance with them which is why I'd prefer to atleast be friends with someone before it evolves into more.
The thing is we keep looking weather we want to or not, it's human nature unfortunately. Just walking around a store you think "hey she's kinda cute" but who in their right mind risks going after someone you know nothing about at all. Just because she attracts you that dosent mean there arn't 5 things about her you'd immidietly hate about her that arnt evident. (ie, drug user, alcoholic, tattoos, mental instability, chews bubblegum, golddigger, etc.)
When people say you need to like yourself first before other's will I find that ridiculous because it dosent take into effect that I could be my own biggest fan and look like some kind of slug creature, the only woman that might like me then would have to be blind possibly deaf. There is somethingto be said for having charisma if you arnt always down on yourself but that's only a tiny portion of the relationship equation.
