Some teens have trouble with social interaction, with the reasons behind it varying. Since social interaction is necessary in order to succeed, it's important to learn how to cope with shyness and social anxiety. Consider working with a friend or a family member of close age to develop your social skills. It may not replace new social exchanges, but it's good practice.  Autistic teens and other disabilities/mental illnesses such as ADHD,  or social anxiety disorder, may have notable difficulty with social interaction. If you're an autistic teen, try learning how to develop better social skills, read other people's body language, and understand figurative language and sarcasm—it's important to learn how to interact in a neurotypical world.  If you have ADHD or related disorder, you can learn to not interrupt others, dominate the conversation, focus on the other person or task at hand, etc. towards those you don't know well. Every day, you'll likely see people you don't know, whether it be in school or out in public. It may seem funny to make fun of those that you don't know, but it's rude, and word will get back to them eventually. Later in life, you'll have to work with people you don't know; it's best to be polite towards strangers. If you can manage it, be friendly as well. It's appreciated by those around you, even if you don't see it.  If somebody you don't know has a clumsy moment that makes others laugh at them, such as dropping their books everywhere, don't laugh, and instead help them pick them up if you have the time. It's a nice thing to do, and they will likely appreciate it, even though they may not show it. . You don't need to be at the top of the social food chain and know everybody at school, but you should at least try to have a few loyal friends throughout your teenage years. Friendships are a good place to build your social skills, and building stable relationships with others can help you determine what you want in friendships and romantic relationships you may pursue.  And most importantly of all, life is simply easier and brighter with friends. Make sure your friends make you feel good about yourself and don't get you in trouble—you want to enjoy your teen years, not spend them miserable because of your "friends"!   Find friends who make you feel good and inspire you to be your best. Hang out with friends you really like, and worry less about maintaining relationships with people who don't improve your life. Friends come and go, and you may have different types and numbers of friends. That's okay. How many friends you have isn't important; it's the quality of the friends you do have that matters, as cliché as that sounds! If you struggle to find friends, try looking in areas where people are similar to you. Are you LGBT, for example? See if there's a teen LGBT group in your city, or if your school has a GSA that you could join. If you prefer writing over socializing, see if you can find writer's groups. If you're autistic, try seeking out other autistic people to befriend. Try going on social media if you can't find friends face-to-face. However, be very careful with this. Online friendships develop much differently than face-to-face friendships, and many people online are not who they say they are—you never know what goes on behind the screen. Sometimes it may not be even an actual human you are talking to. Exercise caution when making friends online, and never agree to meet up with somebody in private. Avoid giving out personal information to people you meet online unless you are sure that they can be trusted.  It is best to meet people in real life first before meeting them on the internet. Some—but not all—teens are interested in romantic relationships, and may want to find a partner. If you get into a relationship, take it slowly and communicate with your partner well. This leads to the healthiest relationships in the long run. You don't need to be tethered to your partner, either. Make sure the relationship allows the both of you to have your own friends and interests. You don't need to rush into anything before you're ready.  If your relationship ends, it's not the end of the world. You may be tempted to swear off of dating forever, especially if you were badly hurt, but keep an open mind. People grow and change. A relationship that would have worked six months ago may turn out to be extremely destructive now. And remember, few couples stay together during or after high school, whether it's because of long distance or other factors. Be wary of abusive relationships. If you feel like you have to constantly walk on eggshells around your partner to try and avoid them getting angry at you or hitting you, or if you can't talk to anybody else without your partner accusing you of cheating, these are huge red flags that the relationship is unhealthy and that you need to get out of it! The same applies for toxic friendships. Family members—especially parents—probably worry about you during your teenage years. Many teenagers become sullen, withdrawn, and stop valuing family as much as they used to. Try to avoid this. Family is one of the most important connections in your life—it's the building blocks for all relationships you develop, whether they're friendships, romantic relationships, or a family that you choose to have later on in life. And plus, you see them every day—why not make it nice to spend time with them?   You don't have to be best friends with everyone in your family, but be kind to them and spend time with them once in a while; play a video game with your sister, help your brother with his writing, offer to go on a walk with your mom, or play a board game with your dad. Don't just stay in your room all day and only see your family at meals. Improve your relationship with your siblings. It's fine to argue and bicker with siblings here and there, but remember that your sibling relationship is usually one of the longest in your life. Siblings can be great allies, mentors, and friends, not just now, but also when you're old and grey. Watch out for abusive family members. Your family can be some of the closest friends you have, but they can also negatively impact your life. If your parents constantly make you feel down, they may be emotionally abusing you. If your brother constantly hits you, that's a sign of physical abuse. Usually, talking things out with a close friend or confronting your abuser can lessen the hurt, but know when to report child abuse. Keep close to your extended family, such as your cousins, too; make an effort to spend time with them when you can. You probably don't see your extended family often, so take advantage of the time you do have to hang out with them!

Summary:
Work to improve your social skills. Be polite Have a few close friends Take romance slowly. Keep good relations with your family.
