You know how everyone keeps saying to go to college, get a degree, and the world will open before you? Check the economy trends first.

 Don't end a book on a bad chapter.

 Your father is an asshole. He's going to hurt you, abandon you, and make your life a living hell. But you'll make it out on the other side tougher than ever before

 Everyone will turn against you.

 Don't waste those 3 years loving someone who in incapable of loving you back. You find the man of your dreams later in junior year anyway. (P.S. He becomes your gay best friend in the end)

 Your life won't be easy, you'll have to handle lots of problems that many teenagers usually don't have, you might have to leave some projects but it's going make you a great winner, someday...

 Don't believew him when he tells you that he's going to leave his wife for you. You will waste five years of your life waiting.

 You're going to discover that the most rewarding part of your education was the time you spent away from school. Don't let it define who you are; nobody else judges you by that standard.
