-Make friends and have some fun!
-Get your facts straight, if your having a conversation don't make anything up it'll make a terrible impression on anyone you're trying to befriend. It's OK, to say I don't know, please tell me. People will be more likely to trust you and believe you when you talk about something you do know.
-Try to make as many friends as you can but make sure you try to get friends that are good influences.
-A good conversation starter is asking about their summer. Don't be shy, either.
-Sometime during the summer, visit the school and learn your way around.
-Do not play any pranks on your teachers. You may think it's an attempt to break the ice; they'll just see it as "one of those kids that will hate learning," causing the student-teacher relationship to have a rocky start.
-Consider carrying mints to keep your breath fresh.
-If you don't know the school rules yet, play it safe.
-There's a big chance that you're not allowed to run in the halls.
-Style your hair for school; it will make you feel and look great.
-Try to get a haircut about two weeks before starts, so you have time to grow comfortable in your new haircut. It's risky to get your haircut the night before; you could hate it, which will lower your confidence, or it could look terrible, and first impressions are important.
