This is an easy process, just a few steps to help you stand out, in a good way.
This is the steps
Always look your best. You don't have to look like a model, or a Plastic, but always present the very best image of yourself where ever you go, and whatever you do. Practice good personal hygiene, take good care of your clothes and accessories.
Cultivate a good attitude and be good natured about things. Sadly not everyone will love you or be singing your praises, there are a lot of haters out there. But acting like a pompous Diva (see most of MTV's Sweet Sixteen for examples), will not get you many TRUE friends and supporters. Just think that for every 3 people who don't like you, 10 think you are wonderful!!
Believe in yourself. If you think you want to try out for a team, do it! Even if you don't make it the first time, if it is something you really want to do talk to people involved in it and find out what you can do to improve your chances next time. Not only will this help form relationships with people who may be the deciding factors, but you will also be showing people that you don't think you are better then them and are always ready to improve on what you already have.
Don't try to become someone you are not. All you can do is be the very best you.
Think happy thoughts. Happy thoughts make you happy, which in turn creates positive energy, and everyone wants to be around that kind of energy.
Be inviting. As great as the image of the cool, aloof beauty everyone falls over, its not exactly real life. Invite people into your space. Strike up conversations with people closest to you. When you walk down the hall or across campus, smile and sincerely say "Hi!" to everyone who meets your eye. Not only will the eye contact cause them to remember you, but they will remember you as being a nice person.
Speak in a normal tone. Some people, when they want to be noticed, tend to speak loudly or laugh too much. You want people to notice you, not your act.
Do not try too hard. A. Because people can sense this from a mile away, and its kind of a turn off. and B. Because when you try to hard it gives you more opportunities to foul things up. Don't force it. If you don't know what to say, simply smile and listen. People like listeners, and sometimes (with certain people) even if that's all you do, they feel a connection with you, simply because you made them feel good.
Be fun and have fun! This does not mean like acting like an air head or ditzy, but it does mean that if you are, for example, at a dance... that you are out there on the floor having the time of your life! Who cares if you can't dance? Do you know how many people think they can't dance either?! Just have fun and don't let yourself worry about what everyone else is going to think.
Being the center of attention often requires you to act as a Leader, so Do not feel that you always have to follow the crowd. If people are ganging up one someone, do not follow suit. Even if you think the people are the coolest, most popular people to grace the earth and the person is the lowest of the low, you do not want to associate yourself with that kind of behavior. Create a diversion that draws everyone's attention to something better, like yourself :o)
It can be emotionally and physically draining to be the center of attention all the time, so be willing to step back and let others shine. Trust me, there will be more then enough time for you. And no one likes an Attention Whore.
