"Not everything that is faced can be changed, but nothing can be changed until it is faced."

Sometimes life allows the opportunitie for you to change the horrible mistakes that you have committed. But nothing can be changed unless it was allready there to be changed in the first place.

Ninjas are the only exception to this quote. Because nnijas can see into the futur, they are able to see possible flaws in an assassination before it happens. Being able to see into the futur is a very valueable skill that has saved many a ninjas lives.
