How to Write a Poem

Reading Rexroth, I wonder
Do I want to learn
How to write a poem?

Multi-meter lines 
Pentametric or trochee,
Or syllables in sevens
and nines as Rexroth did?

Triolet, dizain, villanelle
Sonnet, sestina, roundelle
Ode, elegy, and pastoral?
Ghazal, haiku, or prayer?

Rigid form or what
They called blank verse
When Walt wrote it
Open, honest, truthful?

How much knowledge
Must I cram into my brain
To spoil my poetry?

Or do I just want to write?
