How do I get a guy to notice me?

You know there's a pretty good sized group of guys that have a very similar problem. The difference? They're expected to approach a girl and risk being rejected. Be glad you don't have to worry about that aspect of it :P

What about you don't you like? What are you feeling insecure about? There has to be a reason you have lower confidence, right? If there's not (and there very well might not be) then you might want to explore that a bit and find out why you feel that way.

Maybe try to find something you can be confident about. Do you do something well?

Sorry if I'm not too helpful, it's not an easy question, lol. Some people just seem to have it come too easy, but from what I see they are often more selfish (they don't care what other people think). You have to find a way to believe in yourself. Just remember it's not being bitchy or an asshole that people like, it's the energy, personality and confidence.

If you continue like this, the chances are you will get talked to by someone who notices you even beyond your mask of shyness and self-consciousness.

A quick fix for your situation would be to tell guys you talk to that you're extremely shy and to not think you're ignoring them, this way they won't think you just aren't interested in them.

You have to make eye contact or at least look at people. If you never look at a guy he figures your not interested and he will go for someone who looks interested.

In my opinion guys and girls both like to go for the hard to get type. its human nature, you want what it seems you can't have. try walking around straight and smile at people. ever hear that saying "when your smiling, the whole world smiles at you"? its most of the time true. do not turn out to be like your kid sister though. because then it would not be you acting as yourself. everyone is unique in their own way and somebody will like you for who you are! good luck

Confidence is what makes a girl sexy. Have you ever seen girls who pull a lot of guys, but they are not the best looking ones? They are happy, easygoing and are confident. People can sense who has low self esteem and who doesn't. It's like an aura around you.

Your sister sounds kind of mean, but some guys mistake stuck up-ness for confidence.

First of all. People don't like people such as you described your sister to be. Guys at that age aren't "savvy" about what they like yet. Be who you are, and DO stand up straight. Look at yourself in a mirror sideways and see yourself slouched over like you're used to and then see yourself standing straight. See how much thinner you can look as well as confident. It will strengthen you tummy muscles at the same time. Another reason to avoid slouching is because us girls can get oestroperoisis and standing straight can insure you won't have that hump old ladies get, you know?
But for sure check yourself in the mirror and see for yourself. It takes 21 days for a human being to get used to something, i.e. Walking straight and tall. Good luck.
