Poetry began as communal, as a way to unite the tribe, in shared stories, history.
Now there is an element of the outlaw in it, possibly because it touches on truth, not something highly valued in today's society.
Despite that, consider the words of Muriel Rukeyser.
"Breathe in experience. Breathe out poetry."
One man at the Sharon Old's workshop could not find a pen when just the right thought came to him. His wife dug through her purse. He almost wrote his poem in eyeliner. One needs to want it that much, to put down one's words in song on whatever comes along. Write on bark, stones, toilet paper. Write on what is around, all that surrounds, within and without.
