Life is tons of discipline. Your first discipline is your vocabulary; then your grammar and your punctuation Then, in your exuberance and bounding energy you say you're going to add to that. Then you add rhyme and meter. And your delight is in that power.
Robert FrostWhen a friend calls to me from the road And slows his horse to a meaning walk, I don't stand still and look around On all the hills I haven't hoed, And shout from where I am, What is it? No, not as there is a time to talk. I thrust my hoe in the mellow ground, Blade-end up and five feet tall, And plod: I go up to the stone wall For a friendly visit.
