What does the line mean "Still, that's better than a poke in the eye with a sharp stick" in the writing of Somerset Maugham?the line has a...

It is a difficult question to answer because I don't
believe that Maugham ever makes it quite clear what it means idiomatically.  Literally
it just means something along the lines of "could be much worse."  In "The Lotus Eater,"
Wilson utters the phrase when he compares the twenty five years he will have on the
island to the forty that "the mythical German" had after falling in love with
Capri.

Idiomatically it appears to go along with some of
the bent of the story.  Much of the feeling of the story is about the way that things
could be worse or this idea of Wilson who decided to take the simple road to happiness
and had planned on ending his life when the funds to keep him safely and in the form he
desired ran out.  The narrator is curious about him and thinks hard about what his life
is like, whether he has made the appropriate choice, etc.  In some ways this may very
well relate back to Maugham's use fo the phrase as it signifies that choice between
something pretty good and something that sounds downright
horrible.
