First off, while you're still going to school, don't focus on boys or trying to be in a relationship. It may look like a lot of fun, but assuming you are slightly younger, nothing good usually comes out of temporary relationships. Focus on your school work because that will do you way better than any boy will ever do you. Please don't ever forget that. If you try to rush relationships you more than likely will end up settling for less just because you want to feel like you have someone. (Speaking from experience) However, with your question I will try to answer that. Be nice, and friendly. Smile a lot, and be a good heart-ed person. Apart from that and being who you REALLY are, there's nothing much else you can do. Please try to consider my advice, I think it will really help.
