True leadership means making tough decisions today for a better tomorrow.

In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed.  

"I never think about what could go wrong. I only focus on what I need to do right."

一件事情都不能做到有始有终，就不要去操持其他的事情;一物也不明白，就不要追求博闻广记。

The greatest crimes are not committed by those who break the rules, but by those who follow them to the letter.
