The truth is you don't know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed.

The past is always tense, the future perfect.

译文：做事的时候一定要多替别人着想，读书时一定要切实地下足功夫。赏析：为人处事不能自私自利，不能只顾自己安逸舒适，而要学会换位思考，只有这样，身边才有很多人尊重我们。读书须用功，一字值千金。读书学习要甘于忍受寂寞，才能学有所成。

"To be human is to be unfinished, to be always becoming."
