Look at the world you center. Do you take great pride in it? Do you sweep the sidewalk at the storefront of your life daily, at daybreak? Do you polish the doorlatch to your home and straighten the welcome mat for friends and enemies? Do you feel you have the opportunity, nay the responsibility to aim to be the very best [enter your job title here] that ever walked the earth? If so, kudos to you. If not, get to it. (And have a wonderful day.)
