The dead are our silent collaborators in the quest for knowledge.
Every setback is a setup for a comeback.
命题是断言某事是或不是事实的陈述。
Challenges are opportunities in disguise; embrace them with courage.
Every soul is immortal.
Those who make peaceful revolution impossible will make violent revolution inevitable.
The more you know who you are, and what you want, the less you let things upset you.
