Simplicity

The ability to simplify means to eliminate the unnecessary so that the necessary may speak.

(Hans Hoffman)

When Hoffman said this he was talking about painting but I think that this quote equally applies to poetry. Good poetry is all about eliminating the unnecessary words and creating space (like Hoffman's light) for the ideas to breathe and grow in. The words are like colours in a painting if you pile to many on or crowd them too close together they become muddied and lose some of their beauty.
