State a generalization about life based on the following passage:
“The end of their argument was that they sent Fili and Kili to look for a better shelter. They had very sharp eyes, and being the youngest of the dwarves by some fifty years they usually got these sort of jobs (when everybody could see that it was absolutely no use sending Bilbo). There is nothing like looking, if you want to find something (or so Thorin said to the young dwarves). You certainly usually find something, if you look, but it is not always quite the some- thing you were after. So it proved on this occasion.”
