Don't wake your grandma up by fall through a window when your sneaking back inside at three in the morning.
If someone tells you no, tell them yes and do it anyway.
Don't be friends with somebody if they make you miserable, they might be fun sometimes but a friend shouldn't make you feel bad about your self.
Don't focus on embarrassing things from the past, nobody else remembers it.
Focus on what makes you happy, if you ignore the bad things in life, chances are you'll be happier in the end.
Always remember that there's more in this world than just your town, go explore.
Never forget that somebody loves you, you just might not know it yet.
