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 FrostThe Armful For every parcel I stoop down to seize I lose some other off my arms and knees, And the whole pile is slipping, bottles, buns, Extremes too hard to comprehend at. once Yet nothing I should care to leave behind. With all I have to hold with hand and mind And heart, if need be, I will do my best. To keep their building balanced at my breast. I crouch down to prevent them as they fall; Then sit down in the middle of them all. I had to drop the armful in the road And try to stack them in a better load.
