今天很残酷，明天更残酷，后天很美好，但绝大部分人是死在明天晚上，所以每个人不要放弃今天。
Today is cruel, tomorrow is crueler, and the day after tomorrow is beautiful, but most people will die tomorrow night, so don't give up today.
"Life is not a series of gig lamps symmetrically arranged; life is a luminous halo, a semi-transparent envelope surrounding us from the beginning of consciousness to the end."
The past is always tense, the future perfect.
The joy of discovery in mathematics is like solving a puzzle that the universe has left for us.
不沉溺于过去，专注未来。
写作就像在镜子前裸露灵魂，不惧怕它映照出的影像。
