Making friends can be difficult, especially these days with so much peer pressure(同龄人之间的压力). If you want to develop a more pleasing personality and make friends, become  genuinely(真诚地) interested in other people. Show kindness. You may be wearing the latest  designer label clothes, the hottest brand shoes, and the coolest jewelry, but if you display sourness  and selfishness, you'll have a battle ahead of you to make good friends.Smile, smile and continue to smile. It costs nothing, enriches those who receive it, and  happens in a flash but the memory lasts forever, it creates happiness in the home and classroom. A smile can not be bought, begged or borrowed; it comes from the heart. If you want other people to   like you, make the other person feel important - and do it sincerely!Choose your friends carefully. If others try to persuade you to smoke, take illegal drugs, steal,gamble, fight etc. dare to say NO. Doing the wrong thing is the quickest way to lose friends,especially honest, good and upright friends.

Being mentally strong is not always easy, but let me assure you that the more you practice it,__________. Soon those who thought they were trendy will want to dress like you, talk like  you and be with you, because you have a personality which is different. People like being different!By being an individual with your own personality, you can achieve the very best experiences in   your life.

You may not ever have many friends, but let me tell you that it is better to have one good  friend than ten dishonest friends who will stab(伤害)you in the back at the very first opportunity  that arises.
