Read back the work to yourself, and then to imaginary members of your audience. Put yourself in their shoes. Get the tone right, the choice of words, the structure of the piece. Poems must communicate. Have timetables, but don't be afraid to follow hunches and new directions.
Poems develop as their internal structure directs.
Distill the essence of your piece. Find its centre of gravity, what you are really trying to do. Engage in a continuous dialogue with your productions. Imagine them being read by others, perhaps people contemptuous of your work. Redraft for attack and freshness.
