Leadership is about making others better as a result of your presence and making sure that impact lasts in your absence.

"We are all haunted by something, aren't we?"

一支最甜美的歌，往往是用于歌颂最悲伤思维的歌。

重要的不是你被击倒多少次，而是你能重新站起来多少次。

The only thing we can know is that we know nothing and that is the highest flight of human wisdom.
