Well I was about to be expelled from school, I had been arrested and a teacher said: "Why don't you try acting, instead of distracting the class? Why don't you use your comic talent for something more productive?" My maths teacher suggested I do comedy and I decided to have a go. I pursued it after that. I was about 17.
Another way of saying "put it in the Book" would be that each poem we write pops up in the city of poetry, where anyone can visit it. Just as we visit the poems written before us. Go to Dickinson's house, or Li Po's or whomever we think has something to say to us that might help or be beautiful.
