Now when I think about the time before the college entrance examination, I still feel very excited, but I have never been able to muster the courage to go back to the playing field. I am afraid that the person I am now is not worthy of the hard-working myself at that time, and I am worried that the occasional trials now are no longer worthy of the passionate young man at that time. Time flies very fast, and the mood at that time is still there, but people have become very blurred. Everyone says that things have changed, and it seems to be true.
