Step one, choose your topic. Likely yourself. Because what greater subject could there be? None surely.
Step two, choose an image. Find something that can serve as a metaphor for you. Find the rain forest for instance. Or perhaps a pond frozen over in winter.
Yes, these should serve nicely.
Step three, place yourself somewhere in the midst of these things. Let you be the trunks of the trees supporting the lush, green canopy. You, poor, tired, supporting the thick boughs that are the real life meters and meters and meters above you. Or is your face the ice of the pond. All that people ever notice is how much you can take before you break. But there is so much more just beneath the surface. So much teeming with life. No one knows how deep you go. No one will know until the ice thaws (which is unlikely to happen anytime soon. but the metaphor was never meant to extend that far.)
Step four, write yourself in to the piece in such a way that no one else will be able to identify you. (Unless they're **** cunning.) Perhaps disguise your identity within the purpose of the piece or the flowing imagery seeping through the spacious cracks in your technique. Riddle the work with subtle ins and outs and minute complexities that vex the reader away from your intentions.
Nicely done.
Step five, ruminate. contemplate your reflection as it appears in your monitor. Not the image of your face bouncing off the glass but the snapshot of your thoughts so opaquely back-lit. Remind yourself that this is for you and no one else. Proofread. This is just for you and no one else. Revise. This is just for you and no one else. Justify this is just for you.
Step six, post to a public forum.

Surprise! The poem is about me! See? It's satirical. Sorry it was so long.
