A Life is like a Box of Chocolates

"Mama always said life was like a box of chocolates. 
 You never know what you're gonna get."

by Forrest Gump

the lead character of the 1994 film Forrest Gump

"You know, they've got these chocolate assortments, and you like some but you don't like others? And you eat all the ones you like, and the only ones left are the ones you don't like as much? 

 I always think about that when something painful comes up. 
"Now I just have to polish these off, and everything'll be OK.
  ' Life is a box of chocolates."

In the book Norwegian Wood by Haruki Murakami
