On writing poetry, I had a student write that "If you cannot tell how you are feeling, write whatever is on your mind. If you are angry, write about it! If you are depressed, write about it. If you are overcome with happiness, WRITE! , one day someone will read it and love it, connect with it, and make a connection with you, too."
"I appreciate your optimism! Usually writing poetry is a bit more like trying to fill the Grand Canyon with dandelion fluff."
