Go to your bookshelf and pick out one of your favorite books. It doesn't have to be a poetry collection—any book will do. Write down the first line and the last line of the book. Use the last line of the book as the first line of your poem. Then, write until the first line of the book makes sense to use as the end of your poem. Use the lines as guides for a start and finish, but give your poem a unique theme, different from the original book.
