Success is not about how much money you make, it's about the difference you make in people's lives.

出自北齐·颜之推《颜氏家训·勉学》。不得，不能、不可。雌黄，矿物名，可作颜料，古代用以涂改文字，后引申为信口更改、随便乱说。没有读够一定数量的书，对前人的见解没有彻底了解，是不能随便乱下结论、乱发议论的。书要多读、话要谨慎；应当谦虚向学，不可妄自尊大。

成功就是带着热情从一个失败走向另一个失败。

Science is about pushing boundaries, both in knowledge and technology.
