Dear Little Sister,
Take your time in life. Don't rush to grow up because you want to do everything I am doing. You will have your time and it will great, but enjoy your time in high school. You will miss it when it is gone; trust me.
Don't ever let a boy make you feel like you are not good enough because you are worth the entire moon and stars to me. Boys will come and go; and some day you will find the right one. But it's okay if that's not today. You will go through your first love and plenty of heartbreaks. It will be hard and you will cry, but remember you are so much more than all of that. You have so much ahead of you.
Go to school; you will learn more than you will ever know there. You will learn a lot of lessons outside of school as well but the only way for you to gain your career in life is to succeed in school. I know I don't say it enough, but god you are so intelligent. I have seen your brain work and it is a force of nature. All you have to do is work a lil bit harder and direct that towards your studies and you would be unstoppable. Do not let anyone tell you that you are not smart. I promise that you are.
This is the time where you are going to start developing who you are and who you want to be in life. Be a good person like I know you are. Just be great. I will love you no matter what.
Love,
Your Big Sister
