You’re a person. You’ll make mistakes. You’ll grow. You’ll mature. You’ll develop both mentally and physically. You’ll develop a tolerance for all of the bullshit you have to endure in the world. You’ll regret a lot of the decisions you’ve made up until this point in your life. You’ll say things you don’t mean. You’ll waste time loving an undeserving person. You’ll lose friends, and gain some. You’ll be depressed, upset, angry, and overall anything that isn’t happy all the time.
