“As for writing, that's a cruel hard business. Unless you're very lucky it'll break your heart.”

“Devoted though we must be to the conservation cause, I do not believe that any of us should give it all of our time or effort or heart. Give what you can, but do not burn yourselves out -- or break your hearts. Let us save at least half of our lives for the enjoyment of this wonderful world which still exists. Leave your dens, abandon your cars and walk out into the great mountains, the deserts, the forests, the seashores. Those treasures still belong to all of us. Enjoy them to the full, stretch your legs, expand your lungs, enliven your hearts -- and we will outlive the greedy swine who want to destroy it all in the name of what they call GROWTH.God bless America -- let's save some of it.Long live the weeds and the wilderness yet!”

“Better a cruel truth than a comfortable delusion.”

“Men come and go, cities rise and fall, whole civilizations appear and disappear-the earth remains, slightly modified. The earth remains, and the heartbreaking beauty where there are no hearts to break....I sometimes choose to think, no doubt perversely, that man is a dream, thought an illusion, and only rock is real. Rock and sun.”

“But hell, I do like to write letters. Much easier than writing books.”

“A writer must be hard to live with: when not working he is miserable, and when he is working he is obsessed. Or so it is with me. Thus my writing life consists of spells of languor alternating with fits and spasms of mad typing. At all times, though, I keep a journal, a record book, and most everything begins in the form of notes scribbled down on the pages of that journal.”

“So I write mainly for the fun of it, the hell of it, the duty of it. I enjoy writing and will probly be a scribbler on my dying day, sprawled on some stony trail halfway between two dry waterholes.”
