You can be friends with people your whole life and then wake up one day and realize that you need to move on. If you're sitting at lunch with them and you feel like you don't fit it, you're allowed to sit somewhere else.
2. Loving someone and loving the attention they give you are two completely different things. You don't love that boy who sits behind you in math, you just love that he calls you pretty. It's okay to want to be called that, but learn who will be there for you in the middle of the night when you feel sick to your stomach because your friends decided to make plans without you.
3. Your mom is right. Whether it be about going to bed before two in the morning on a school night or that senior boy with the really good hair at all the parties with a red solo cup in his hand, she's right. You're not going to listen to her at first, but when you come home a sleep-deprived mess with a broken heart, she'll be there to pick up the pieces.
4. Your grades are important. No, you shouldn't stay up all night and slave over your algebra homework, but try and do good, even when everything's a mess.
5. People will tell you, "please don't ever change!" Don't listen to them. Change a million times, change every day, every hour, every minute. Change for the better, grow to be a bigger and stronger person. Don't listen to anyone who wants you to be stationary, they're holding you back.
6. It's okay to fall apart every once in a while. Don't think you have to have it all together, you've got so much time to figure all of that out. If you need to cry a little bit, that's okay, and if you need to scream into your pillow, that's alright too. It'll all be okay in the end.
7. You're going to learn that people aren't going to take you seriously. That's okay, work hard to prove them wrong.
8. You're still a child, please don't make a huge fuss over it when people call you one. You don't have much longer and you're really going to miss when your mom would make you dinner and your dad paid for your phone bill. You don't have that many responsibilities and you have so much potential still. Be a child and be okay with it.
9. Don't litter your body with drugs and alcohol because the cute older boy does and you want to fit in with his crowd. Stand out on your own and they'll notice you for things you can be proud of.
10. They're not staring at you. They're not laughing at you. Keep walking with your head up, just because you think that your hair is too big today or your clothes don't fit right doesn't mean anyone else notices. Keep walking.
