The struggle itself towards the heights is enough to fill a man's heart. One must imagine Sisyphus happy.
The known is finite, the unknown infinite; intellectually we stand on an islet in the midst of an illimitable ocean of inexplicability.  
No man's knowledge here can go beyond his experience.
我不是榜样,我是个警示故事。
释义:别人称赞我,不值得高兴;别人批评我,也不值得生气。
无论你在哪里处于人生的哪个阶段,如果可以,请拿出你的时间、天赋以及金钱,做你力所能及的事。
