外交不仅是国家之间的事务，也涉及到全球问题和全人类的利益。

The world is a very malleable place if you know what you want.

真相很少是纯粹的，也从不简单。

If you are ready to give up everything else and study the whole history and background of the market and all the principal companies whose stocks are on the board as carefully as a medical student studies anatomy—if you can do all that and in addition you have the cool nerves of a gambler, the sixth sense of a clairvoyant and the courage of a lion, you have a ghost of a chance.

Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work.

And when your stomach is empty and your mind is full,it's always hard to sleep.
