Somatic
To write a poem that reflects your essence, do not sleep.
Ask yourself what questions lay unanswered in your mind, what curiosities befuddle you about your existence. Think about these questions and go about your day as usual. Do the mundane and the crucial tasks that keep you busy in your waking moments, but do not sleep.
Do not sleep until you are tired - when your body surpasses exhaustion and only a desire for reprieve from the waking world begins to pull you. This should happen in the early hours of the dawning day, when others are already deep in slumber. Lay in your bed, close your eyes - but do not drift off into that other world until you ask yourself once more, what has been bothering you? What questions do you need answered? Think of this as you go, and when you wake, write what you can remember. See what answers you found, within your own wisdom come morning.
