1. Your GPA doesn't matter as much as you think and most employers won't even ask you what it was.
2. It's ok if you are still finding yourself and don't know exactly what you want out of life.
3. The things you think are great and can't live without will be something you forget about a year from now.
4. Don't do things your parents, family, or society expect out of you if it's not something you want.
5. You don't always have to be happy and that's ok. It's ok to be depressed. Sometimes life sucks, but it will get better.
6. Don't get rid of your dreams because they seem unrealistic. Nothing is stopping you from accomplishing what you want.
7. Relationships aren't all about you. Think about the other person you are with and their feelings.
8. Have fun and don't take things too seriously. Life will only get more complicated and filled with more responsibilities the older you get.
9. Don't lose touch with your friends, you'll regret it when you lose those friendships after college is over.
10. Everything will be ok. You'll make some mistakes but you'll get to where you are wanting to go.
