Being a teenager is a great time to find out who you are and what you value in life. Would you rather be in the chess club than on the football field? Do you like a band that most people at your school have never heard of? Being different and distinguishing yourself among a crowd of people is important -- express yourself and your individuality, and don't make any apologies for who you are. To gain confidence, you've got to feel comfortable in your own skin. You can't please everybody all of the time, so don't waste another minute trying to conform to what's popular. Stand tall and be proud of the person you are, and your positive attitude is bound to turn a few heads.
While you want to stay true to the person you are, work everyday at becoming your best self. Try to be friendly and outgoing to everyone, and stay upbeat, even when you have a bad day. When the timing is right, voice your personal opinions and beliefs. Your friends might disagree with you, but speaking assertively and enthusiastically about your beliefs is attractive, and they'll at least respect you for your candor. Above all, have some fun and live in the moment. Happiness and smiles are infectious, so it's likely that girl you like will smile right back at you if you flash her a grin.
