I compelled myself all through to write an exercise in verse, in a different form, every day of the year. I turned out my page every day, of some sort--I mean I didn't give a damn about the meaning, I just wanted to master the form--all the way from free verse, Walt Whitman, to the most elaborate of villanelles and ballad forms. Very good training. I've always told everybody who has ever come to me that I thought that was the first thing to do.
