In my opinion, being teenager nowadays is very hard. You always have to keep your mind clear, because there are a lot of people, who will judge you, but you have to stay strong.
Except of people's opinions and thoughts about you, you have to study well and to be polite to your parents. But you know, this is hard too, because you are always stressed and there are a lot of abuse around you.
In conclusion, being teenager now is a really hard thing. It is much better to be a child, because of having no problems and troubles with people.
