One thing I'd change about my life if I could would (have to) be my last year in/of high school, because I was constantly studying for the university entrance exam; I never got any exercise, nor did I hang out with my friends. I realize now that if I had, I might have been happier and gotten a better grade on the university entrance exam. In looking back, I should have studied less, not just because of the stress, but more so because my life would have been different today.
