Nature is slow, but sure; she works no faster than need be; she is the tortoise that wins the race by her perseverance.
Henry David ThoreauI have seen some whose consciences, owing undoubtedly to former indulgence, had grown to be as irritable as spoilt children, and at length gave them no peace. They did not know when to swallow their cud, and their lives of course yielded no milk.
Henry David ThoreauMen should not labor foolishly like brutes, but the brain and the body should always, or as much as possible, work and rest together, and then the work will be of such a kind that when the body is hungry the brain will be hungry also, and the same food will suffice for both; otherwise the food which repairs the waste energy of the overwrought body will oppress the sedentary brain, and the degenerate scholar will come to esteem all food vulgar, and all getting a living drudgery.
