“How happy is the little stone That rambles in the road alone, And doesn't care about careers, And exigencies never fears; Whose coat of elemental brown A passing universe put on; And independent as the sun, Associates or glows alone, Fulfilling absolute decree In casual simplicity.”

Emily Dickinson
