- I would convince the world that social hierarchy is unnecessary.

- I would tell the world that beauty is subjective, and that we need to stop glorifying it.

- I would tell everyone to be brave and be creative, no matter the talent, no matter how important the person is in society.

- I would tell adults that they cannot demand respect and undermine children's opinions because they don't matter.

- I would tell some teachers to shove their opinion elsewhere because I'm tired of being bossed around.

* But eh, rules are important. We might act like cool teenagers and put up slogans like Rules are meant to be broken but no, they aren't. The silly rules we might choose to break aren't the only ones that can be broken. The world would be in chaos if that was possible. Not the good kind of chaos either.
