Coming into high school, don’t hold the hope that your best friend will still be there because in high school a lot changes.
High school is fun and full of memories but it flies by so fast you don’t realize it so enjoy it while it last.
Join as many clubs, sports and get involved as much as you possibly can you won’t regret it. Don’t try to be someone you are all through school because honestly you won’t see most these people after you graduate ,be you and be proud of it.
If it isn’t going to matter five years from now, don’t let it bother you now it’s not worth it there is other stuff to focus on.
But all in all, have fun, make memories and enjoy these four years because once they are over you will want them back.
