First step: Figure out what you want to say. Second step: Figure out HOW you want to say it. Third Step: Do it. There are many places online that will allow you to put together a book of your works, or you could do it like i did a decade or so ago and type everything out, photocopy it onto some nice paper, put a bplastic binding on it with a thick cardstock front and back cover. I used to publish a fanzine and did a poetry chapbook for everybody that contributed. I then gave them away to the people who contributed, as well as gave a few to friends. I got one back when we were cgoing through my deceased mother in laws things a few years ago. It was an interesting moment. Just do it, you’ll be disappointed if you don’t.
