Many people find it hard to make friends.  小题1: All it takes is for you to get out of your shell and remember that if you love yourself, others will too. Especially being a teen, making friends can be hard or easy depending on several factors．

Relax. It’s all about confidence---if you are nervous or try too hard to look cool you’ll just act strange. So you won’t make many friends. You will stand out as overdoing(做得过分) something．

You have to act as you have had plenty of friends in the past, so even the “cool” ones will want to speak to you. 小题2: Be relaxed．People will like you for passing a peaceful energy．

Make the first move. Don’t be shy because it won’t help you in anything. Look around for people that seem interesting, and go up to talk to them. A good subject to talk about to anyone is music because almost everybody likes music. 小题3:Try not to get deep when you are first meeting somebody.

小题4: Everyone likes to be heard. So give attention to what others say, look straight in their eyes and show you’re paying attention. If this person feels that you’re listening to him, your new friend will enjoy your company more．

Develop friendships. You may talk to someone now but soon they’ll forget you if you stop．小题5: Say their name as often as you can. When you greet them, say things like, “Hey Alex!”，“What’s going on, Sarah?’’ If you do that every day, they’ll be happy that you care about them and remember them, so they won’t forget you and you will be good friends．
