There is a Chinese proverb 難得糊塗 that my dad put up on the wall of our home which he wrote the calligraphy with Chinese ink and paper.  Every day at home, I would see it.  When I was younger, my dad was very angry and frustrated with life.  And I like to be believe that he stared it at everyday asking himself to change, to ignore things that are not important, to live life a little more carefree.
