What Marks a Real Writer

I enjoyed this snippet from an interview with Anthony Snider, the winner of the 2006 Bridport Prize Competition:
 
“To steal a great line from Czeslaw Milosz: ‘I am a poet because I am always thinking
of something else,’” Snider says with a smile. “There is a back burner that is going all
the time, and if someone says something in a conversation that is an interesting turn
of phrase, or I hear somebody put something together that is interesting, I’ll write it
down and put it away in a little journal of snippets... Sometimes poems are
just begging to be written... Everything flows through.”
