Don't fall too hard or too quick at such a young age. Make sure you can trust a guy before giving your everything to him. Also, when it's over.. Don't dwell, you can do better.

 She's not coming back. She doesn't miss you. She cheated on you with two of your friends. Don't kiss her. Don't let her convince you that sex is okay.

 Be more open- minded about choosing your major. You will find out that Chemistry is not for you.

 Don't believe a word he tells you. You are beautiful and have everything to offer. Your life will be so much brighter when you realize that.

 Don't fall deeply in love with him, he's more emotional then you on your period you just don't know it yet. Stay away from him, you'll meet a band kid he's so much better for you- stick with him okay?

 Thank you for not jumping. Life is beautiful.

 Forgive your best friend. Don't lose 2 years of friendship...she was just trying to protect you

 Don't settle for good enough. Life is more interesting than that.
