Highschool is fun, there are a lot of life experiences you will get during this time that change who you are forever, we all have different experiences but I've loved every year of highschool (gets better and better as time goes on,) going into my senior year in a few weeks so yeah.
Be cool and stay in school!
Also be confident, girls love the confidence.
Protip; don't make the mistake 90% of the forumers here made, BE SOCIAL, nothing more depressing than wasting one of the biggest high points of your life playing video games and avoiding people.
