Never try to pursuit any right that one cannot control,
never try to pursuit a love affair that does not belong to oneself,
never try to change an unchangeable fact.
Life is too short, so live it gracefully and happily.
Try to feel it with your heart, and enjoy it.
Really, no need to think too much !

不該追求自己沒有辦法掌握的權利、不該追求不屬於自己的愛情、不求改變無法改變的事實，短短的人生，快樂的活，慢慢的過，用心體會，用心享受。真的不用想太多。
You should not try to chase the rights which are not under your control, you ought not to pursuit the romance which not belongs to you, you ought not to change the fact which is unchangeable. Life is short, so you better live happily and enjoy the process gradually. Please use the heart to feel as well as to enjoy. Not to think too much.

Power is a more appropriate word than right.
