《长歌行》

出自汉乐府《长歌行》

青青园中葵，朝露待日唏。
阳春布德泽，万物生光辉。
常恐秋节至，焜黄华叶衰。
百川东到海,何时复西归。
少壮不努力,老大徒伤悲。

That's the reason why I'm pushing myself so hard at times. I do not want to regret not working hard should I fail to achieve my life aims and goals. I finally have a deeper understanding of this (imo) meaningful statement which my teachers and parents have been trying to teach/tell/explain/educate/drill into my head since I was in primary school.

Now, it serves as a motivation for me to work harder. Afterall, you are supposed to reap what you sow.
