苦难！我们所有美好的品质、生命中的价值都归功于它；我们因它而怜悯，因它而勇敢，因它而拥有所有美德。
Suffering! We owe to it all that is good in us, all that gives value to life; we owe to it pity, we owe to it courage, we owe to it all the virtues.
The safest course is to do nothing against one's conscience.With this secret， we can enjoy life and have no fear from death.
如果你没有偶尔失败，说明你不够努力。
The historian must be impartial, but not indifferent.
