You only live once, but if you do it right, once is enough.

　　若年华未曾虚度,只活一生便也足够.

　　Man struggles upwards; water flows downwards.

　　人往高处走，水往低处流。

　　Live as if you were to die tomorrow. Learn as if you were to live forever.

　　珍惜生活,就像死神随时来临;热爱学习,就像生命能够永恒.

　　Don’t wait. The time will never be just right.

　　始终困于等待，时机就永远不会到来

　　Those who turn back never reach the summit.

　　回头的人永远到不了最高峰!

　　A life without suffering is a life without happiness.

　　未尝苦中苦，何来甜上甜?
