Worth repeating: measure twice， cut once.
这值得说两遍：量两次才切一次。
"Every saint has a past, and every sinner has a future."
我不与任何人竞争，只与自己竞争。我的目标是比昨天的自己更好。
The desires， and other passions of man， in themselves， are in his own power； his real difficulties are， to know when they are to be controlled， and when not.
不要让成功冲昏头脑，也不要让失败打击你的心。
风险管理不是消除风险，而是在可接受的范围内理解和控制风险。
