without hope, the heart would break.
--camden
沒有希望，心靈就會衰竭。
--卡姆登
man's dearest possession is life. it is given to him but once, and he must live it so as to feel no torturing regrets for wasted years, never know the burning shame of a mean and petty past; so live that, dying, he might say: all my life, all my strength were given to the finest cause in all the world——the fight for the liberation of mankind.
--ostrovsky
人最寶貴的是生命。生命每個人只有一次。人的一生應當這樣度過：回憶往事，他不會因為虛度年華而悔恨，也不會因為生活庸俗而羞愧;臨死的時候，他能夠說：我的整個生命和全部精力，都獻給了世界上最壯麗的事業——為解放全人類而鬥爭。
--奧斯特洛夫斯基
man who has a settled purpose will surely succeed.
有志者事竟成。
