Why do "Nice Guys" finish last?

I've been studying all the time these days. But offcourse Youtube vids would come in between. Just then, I was watching this series by WongFuProductions called "Just A Nice Guy". Halfway Part 1, I realised that sometimes "Nice Guys" misunderstood the reason why they might finish last.

1) Wes told Phil: "Girls want something different.They want confidence, cockiness, they want danger.They want a guy that can be their friend sometimes, but not always. Girls like jerks"
My convict: FALSE.

Let me say to you, I know a guy who's really good looking but man he's cocky and overconfident. That's a big BIG turn off!  His looks just disappear beneath all those bad personalities. I agree with confidence, girls do prefer their guy to be confident. If they're not, then why would girls trust the rest of their life in the "hands" of an unconfident guy? Plus, a confident guy would be brave enough to show his feelings to the girl he likes.

Also, I would want a guy who can be my friend all the time. If he and I will be together for the rest of our lives, it would be really lovely to have someone who's also my best friend.

I reckon that nice guys really are attractive (I know that was how I got attracted to my bf teehee). But the thing that makes them stay in the "guy who's my best friend but I will not date" zone is when they're too nice to every single girl they know. And they usually have more girl friends than guy friends.

Don't get me wrong, being nice to everybody is a good thing. But if you like a girl, you gotta treat her differently  (a.k.a nicerrr than other girls) and you gotta give them "hints". Doesn't mean you should downgrade your niceness to other girls though. Does that make sense? Why you may ask? Well, this is cos if you don't give "signs", then girls would've thought that you're just being nice just like how you usually are to other girls.

Girls have insecurities (not a hidden fact at all). So they wouldn't let themselves fall for a guy who's known to be very nice to all girls (in case we mistakenly thought that the guy like us but actually he's just being friendly). I reckon, this is where nice guys fall short. Girls would want a guy who are loyal to them and would love them like we're "the only girl in the world". So if this guy starts treating other girls the same as he would treat us, then it's gonna make us girls question your feelings for us.

That's all I wanna say. I hope it clears up some misunderstanding some guys might have. And I hope that nice guys don't turn into jerks just for the sake of getting a gf. Be yourself, be nice to everyone, but only "flirt" with the girl that you like.

DISCLAIMER: This is purely my opinion. There may be girls out there who likes jerks. But I think that if a girl is serious about a relationship, they wouldn't fall for jerks.Only girls who are out there to find fun would look for jerks. What do you girls/guys out there think??
