I regret wasting my high schol days. It was the worse period in my life. The teachers were very strict, there were few friends, and I was bored to supend monotones days. I didn't have clear goal at that time (and still now...). Now, I think I should have studied abroad while I was a high school student. If I had have done so, my life would have been greater.
Since I am a negative person, I can't think things optimisticlly and I always regret. But I strongly wish I could try my past 3 years once more.
