It only took me about 18 months after high school to realize that absolutely nothing I did in high school was relevant or interesting to the outside world in any way, shape, or form.
After about 3 years, I couldn't even remember my classmates names.
Now, my friends' kids and my nieces are graduating from high school, and I know that absolutely nothing has changed, and - unless you are shot by an angry white american boy - high school will soon be a thing you vaguely remember, like a book you read once for a fourth grade assignment.
Just graduate. Get out into the world and become a participant in this thing called life. Nothing of material interest/value happens in high school. Just get through it.
