Nowadays, people are strongly influenced by social networks, and teenagers are part of this group of people too. We are get in used of using social media and new technologies for everything in our life, and as I see it, that's not really good for us since we are turning into people who depend on new technologies and social networks, which are not as good as can be seen at first due to they can be considered a bad influence for modern teenagers. This is because in this networks are showed certain contents that encourage teenagers to do what everyone at the moment do and to follow the fads.

This is a widely used way in modern teenagers who do what people usually do just only to make friends or to fit in society and gain a reputation without thinking in the consequences.  This way of having a good time and sharing happiness with friends is developing in certain activities which are not good for people's healthy, such as drinking and smoking.

There are many reasons of this teenagers' behavior, such as making friends or trying to fit in society, but there are also some less common reasons, like an unhappy childhood. This last cause produce in teenagers an aggressive and impulsive behavior which leads them into social problems.

Personally speaking you don't have to do things which you don't want to since you have to have our own personality to decide what you want to do in your life.  To my mind you don't have to take the easy way just because everybody chooses it, you have to decide it by yourself.
