Stress
Who ever said high school is the best four years of your life was spinning some interesting lies. Although i have had some of the most fun times of my life so far, i have also had some of the most stressful and painful moments thus far  I'm sure that there are many more horrible things to coe, and more stress than what should be humanly tolerable, but i'll also experience pure unadulterated joy.
Its just. High school is very stressful. Because how well you do in high school dictates how successful you are going to be in the rest of your life according to America's standard.
These tiny four years, and how hard you work during them, how good you are at working the system, how smart you are compared to others, dictates your entire future.
Its just not cool man.
Not cool.
