“Those days in the woods saved my life many a time in combat.”

The Sense of Wonder (1965)
Context: A rainy day is the perfect time for a walk in the woods. I always thought so myself; the Maine woods never seem so fresh and alive as in wet weather. Then all the needles on the evergreens wear a sheath of silver; ferns seem to have grown to almost tropical lushness and every leaf has its edging of crystal drops. Strangely colored fungi — mustard-yellow and apricot and scarlet — are pushing out of the leaf mold and all the lichens and the mosses have come alive with green and silver freshness.

Life Without Principle (1863)
Context: If a man walk in the woods for love of them half of each day, he is in danger of being regarded as a loafer; but if he spends his whole day as a speculator, shearing off those woods and making earth bald before her time, he is esteemed an industrious and enterprising citizen. As if a town had no interest in its forests but to cut them down!

"I spend my days preparing for life, not for death" The Guardian, Laura Smith (2007-10-25)

As quoted in "John Glenn had the stuff U.S. heroes are made of" by Howard Wilkinson, in The Cincinnati Enquirer (20 February 2002).
Context: I don't think many people remember what life was like in those days … This was the era when the Russians were claiming superiority, and they could make a pretty good case — they put up Sputnik in '57; they had already sent men into space to orbit the earth… There was this fear that perhaps communism was the wave of the future. The astronauts, all of us, really believed we were locked in a battle of democracy versus communism, where the winner would dominate the world.
