Teenagers

The positive aspects of being a teen are that you get to experience more things, learn about life & not pay bills;]
The negative aspects of being a teen are that no partying or getting into clubs, it's illegal to drink & well most people will think you're immature.
Some of the major concerns of teenagers are learning how to drive to get out more & hanging out with friends.
These concerns are a bit different then teens then. Teens then were more boring in my opinion. They would be just fine being bored all day.
Advice I would give is to just live life, but know you're limits & when to stop.
