Thoreau writes, 'The really efficient laborer will be found not to crowd his day with work, but will saunter to his task surrounded by a wide halo of ease and leisure. There will be a wide margin for relaxation to his day. He is only earnest to secure the kernels of time, and does not exaggerate the value of the husk.' Think of what a beautiful metaphor this is for not mistaking the husk--the outer accoutrements of productivity like busyness, or a full calendar, or a clever auto-responder--not mistaking those for the kernel, the core and substance of the actual work produced. And he then says, 'Those who work much, do not work hard.' I love that.
