Crisis

   Danger


  Opportunity


   Crisis

As in all languages, new words are often created from concatenations of already known words. One particularly insightful combination is the Chinese ideograph for "crisis" which is composed of two characters, the left one meaning "danger" and the right one "opportunity."

"Out of clutter, find simplicity.
Out of discord, find harmony.
In the middle of difficulty lies opportunity."

Albert Einstein

There is also an old Hawaiian saying that suggests something similar, but I don't have the Hawaiian translation:

"Love and conflict are binding."
